-# General GitLab pipelines configurations for supercomputers and Linux clusters
-# at Lawrence Livermore National Laboratory (LLNL). This entire pipeline is
-# LLNL-specific!
-
-# We define the following GitLab pipeline variables:
-#
-# BUILD_ROOT:
-# The path to the shared resources between all jobs. For example, external
-# repositories like 'tests' and 'tpls' are cloned here. Also, 'tpls' is built
-# once for all targets, so that build happen here. The BUILD_ROOT is unique to
-# the pipeline, preventing any form of concurrency with other pipelines. This
-# also means that the BUILD_ROOT directory will never be cleaned.
-# TODO: add a clean-up mechanism
-#
-# BUILD_PATH:
-# In BUILD_ROOT, we want to separate builds depending on the machine used,
-# typically because we build on a set of dependencies per machine.
-#
-# REBASELINE:
-# Defines the default choice for updating the saved baseline results. By default
-# the baseline can only be updated from the master branch. This variable offers
-# the option to manually ask for rebaselining from another branch if necessary.
-#
-# MFEM_ALLOC_NAME:
-# On LLNL's quartz, there is only one allocation shared among jobs in order to
-# save time and resources. This allocation has to be uniquely named so that we
-# are sure to retrieve it.
-#
-# TPLS_REPO & TESTS_REPO:
-# Git repositories used in the pipeline
-#
-# ARTIFACTS_DIR:
-# Directory used to place artifacts.

-# The pipeline is divided into stages. Usually, these are also synchronization
-# points, however, we use "needs" keyword to express the DAG of jobs for more
-# efficiency.
-# - We use setup phase to download content outside of mfem directory.
-# - Allocate is where quartz resources are allocated once for all.
-# - Libs is where dependencies are built.
-# - Build is where we build MFEM for multiple toolchains.
-# - Test is where we perform a first set of tests on MFEM build.

-Version 4.1.1 (development)
-===========================
-
-Meshing improvements
---------------------
-- The graph linear ordering library Gecko, previously an external dependency, is
-  now included directly in MFEM. As a result, Mesh::GetGeckoElementOrdering is
-  always available. The interface has also been improved, see for example the
-  Mesh Explorer miniapp.
-
-- Improved Gmsh reader (version 2.2), which now supports both high-order and
-  periodic meshes. Segments, triangles, quadrilaterals, and tetrahedra are
-  supported up to order 10. Wedges and hexahedra are supported up to order 9.
-  For sample periodic meshes, see the periodic*.msh files in the data directory.
-
-- Added support for finite difference-based gradient and Hessian approximation
-  in the TMOP mesh optimization algorithms. This improves the accuracy of the
-  Hessian for r-adaptivity using discrete fields, and allows use of skewness
-  and orientation based metrics.
-
-- Added support for r-adaptivity with more than one discrete field. This allows
-  the user to specify different discrete functions for controlling the
-  size, aspect-ratio, orientation, and skew of elements in the mesh.
-
-- Added TMOP capability for approximate tangential mesh relaxation. Added
-  support and examples for using TMOP on mixed meshes.
-
-- Added complete action of the TMOP Integrator to account for the spatial
-  derivatives of discrete and analytic targets.
-
-Performance improvements
-------------------------
-- Added support for explicit vectorization in the high-performance templated
-  code, which can now take advantage of specific intrinsics classes on the
-  following architectures:
-    - x86 (SSE/AVX/AVX2/AVX512),
-    - Power8 & Power9 (VSX),
-    - BG/Q (QPX).
-  These are disabled by default, and can be enabled with MFEM_USE_SIMD=YES.
-  See the new file linalg/simd.hpp and the new directory linalg/simd.
-
-Improved GPU capabilities
--------------------------
-- Added support for Chebyshev accelerated polynomial smoother on GPU.
-
-- Optimized AMD/HIP kernel support.
-
-- Added a Full Assembly mode compatible with Device kernel execution. This
-  assembly level builds on top of the current Element Assembly kernels to
-  compute a global sparse matrix. All integrators supported by element assembly
-  are also supported by full assembly. See the '-fa' option in Example 9.
-
-- Added CUDA support for sparse matrix-vector multiplication with cuSPARSE.
-
-- Added support for BlockOperator on GPU. See the updated Example 5.
-
-Discretization improvements
----------------------------
-- Added support for matrix-free interpolation and restriction operators between
-  continuous H1 finite element spaces of different order on the same mesh or
-  with the same order on uniformly refined meshes.
-
-- Added support for simplices in GSLIB-FindPoints.
-
-- Added support for H1 and L2 element matrix assembly in the mass, convection,
-  diffusion, transpose, and the face DG trace integrators. This is compatible
-  with GPU device execution and is illustrated in Example 9/9p, see the option
-  '-ea'. When enabled, this level of assembly stores independent dense matrices
-  for the elements, and independent dense matrices for the faces in the DG case.
-
-- Added new partial assembly kernels for H(div) bilinear forms, as well as
-  VectorFEDivergenceIntegrator.
-
-- Improved the documentation of the GridFunction GetValue and GetVectorValue
-  methods. Expanded the GetValue and GetVectorValue methods which accept an
-  ElementTransformation argument to support evaluation on boundary elements
-  and, in the continuous field case, arbitrary mesh edges and faces.
-
-- Added new coefficient and vector coefficient classes for QuadratureFunctions.
-  Additionally, new LinearForm integrators were also added which make use of
-  these new QuadratureFunction coefficient classes.
-
-- Added support face integrals on the boundaries of NURBS meshes.
-
-Linear and nonlinear solvers
-----------------------------
-- Added power method to iteratively estimate the largest eigenvalue and the
-  corresponding eigenvector of an operator.
-
-- Added initial support for h- and p-multigrid solvers and preconditioners for
-  matrix-based and matrix-free discretizations with basic GPU capability.
-
-- Added a new IterativeSolverMonitor class that allows to monitor the residual
-  and solution during the solving process of an IterativeSolver after every
-  iteration.
-
-- Added support for the CVODES package in SUNDIALS which provides ODE
-  solvers with sensitivity analysis capabilities. See the CVODESSolver
-  class and the new adjoint miniapps below.
-
-- Block arrays of parallel matrices can now be merged into a single parallel
-  matrix with the function HypreParMatrixFromBlocks. This could be useful for
-  solving block systems with parallel direct solvers such as STRUMPACK.
-
-- In SLISolver, changed the residual inner product from (Br,r) to (Br,Br) so the
-  solver can work with non-SPD preconditioner B.
-
-- Added support for the SLEPc eigensolver package.
-
-New and updated examples and miniapps
--------------------------------------
-- Added a new example, Example 25/25p, to demonstrate the use of a Perfectly
-  Matched Layer (PML) for the simulation of electromagnetic wave propagation.
-  The example defines and solves several indefinite Maxwell problems.
-
-- Added a new Example 26/26p to demonstrate the construction of a matrix-free
-  geometric and p-multigrid preconditioner for the Laplace problem.
-
-- Added a new example, Example 27/27p, to demonstrate the enforcement of various
-  boundary conditions with the Laplace operator. The example shows the procedure
-  for applying Dirichlet, Neumann (both homogeneous and inhomogeneous), Robin,
-  and periodic boundary conditions with either H1 or DG discretizations.
-
-- Added a new miniapp, Navier, that solves the time-dependent Navier-Stokes
-  equations of incompressible fluid dynamics. See the miniapps/navier directory
-  for more details.
-
-- Added a new miniapps/adjoint directory with two miniapps demonstrating how to
-  solve adjoint problems in MFEM using the CVODES package in SUNDIALS. Both of
-  these miniapps require the MFEM_USE_SUNDIALS configuration option.
-  * The cvsRoberts_ASAi_dns miniapp solves a backward adjoint problem for a
-    system of ODEs, evaluating both forward and adjoint quadratures in serial.
-  * The adjoint_advection_diffusion miniapp solves a backward adjoint problem
-    for an advection diffusion PDE, evaluating adjoint quadratures in parallel.
-
-- Ported Example 11p to SLEPc, to demonstrate solving the Laplace eigenvalue
-  equation with the shift-and-invert spectral transformation method.
-
-- Added a simple meshing miniapp, Twist, which demonstrates MFEM's strategy of
-  stitching together opposite surfaces of a mesh to create a topologically
-  periodic mesh.
-
-- Added a new meshing miniapp, Minimal Surface, which solves Plateau's problem:
-  the Dirichlet problem for the minimal surface equation.
-
-- Added partial assembly support to Example 4/4p and Example 5/5p, with diagonal
-  preconditioning.
-
-- Added full assembly support in Example 9/9p.
-
-- Added a new test problem in Example 24/24p, demonstrating a mixed bilinear
-  form for H1, H(curl), H(div) and L_2, with partial assembly support.
-
-- Added weak Dirichlet boundary conditions (Nitsche) to the NURBS miniapp.
-
-- Added a simple mesh editing miniapp, Trimmer, which trims away portions of a
-  mesh based on element attributes. Any newly exposed boundary elements are
-  assigned attribute numbers related to the trimmed element attributes.
-
-- Added device support in Example 5/5p.
-
-- Added the option to plot a function in Mesh Explorer.
-
-Improved testing
-----------------
-- Added a GitLab pipeline that automates PR testing on supercomputing systems
-  and Linux clusters at Lawrence Livermore National Lab (LLNL). This can be
-  triggered only by LLNL developers, see .gitlab-ci.yml, the .gitlab directory
-  and the updated CONTRIBUTING.md file.
-
-Miscellaneous
--------------
-- Added support for ADIOS2 for parallel I/O with ParaView visualization. The
-  classes adios2stream and ADIOS2DataCollection are introduced in mfem as the
-  interfaces to generate ADIOS2 Binary Pack (BP4) directory datasets for the
-  entire spatial and temporal data. In addition, ADIOS2 allows for setting a
-  user-defined number of data substreams/subfiles. See examples 5, 9, 12, 16.
-
-- The integration order used in the ComputeLpError and ComputeElementLpError
-  methods of class GridFunction has been increased.
-
-- Various other simplifications, extensions, and bugfixes in the code.
-
-
-Version 4.1, released on March 10, 2020
-=======================================
-
-Starting with this version, the MFEM open source license is changed to BSD-3.
-
-Improved GPU capabilities
--------------------------
-- Added initial support for AMD GPUs based on HIP: a C++ runtime API and kernel
-  language that can run on both AMD and NVIDIA hardware.
-
-- Added support for Umpire, a resource management library that allows the
-  discovery, provision, and management of memory on machines with multiple
-  memory devices like NUMA and GPUs, see https://github.com/LLNL/Umpire.
-
-- GPU acceleration is now available in 3 additional examples: 3, 9 and 24.
-
-- Improved RAJA backend and multi-GPU MPI communications.
-
-- Added a "debug" device designed specifically to aid in debugging GPU code by
-  following the "device" code path (using separate host/device memory spaces and
-  host <-> device transfers) without any GPU hardware.
-
-- Added support for matrix-free diagonal smoothers on GPUs.
-
-- The current list of available device backends is: "ceed-cuda", "occa-cuda",
-  "raja-cuda", "cuda", "hip", "debug", "occa-omp", "raja-omp", "omp",
-  "ceed-cpu", "occa-cpu", "raja-cpu", and "cpu".
-
-- The MFEM memory manager now supports different memory types, associated with
-  the following memory backends:
-  * Default host memory, using standard C++ new and delete,
-  * CUDA pointers, using cudaMalloc and HIP pointers, using hipMalloc,
-  * Managed CUDA/HIP memory (UVM), using cudaMallocManaged/hipMallocManaged,
-  * Umpire-managed memory, including memory pools,
-  * 32- or 64-byte aligned memory, using posix_memalign (WIN32 also supported),
-  * Debug memory with mmap/mprotect protection used by the new "debug" device.
-
-libCEED support
----------------
-- Added support for libCEED, the portable library for high-order operator
-  evaluation developed by the Center for Efficient Exascale Discretizations in
-  the Exascale Computing Project, https://github.com/CEED/libCEED.
-
-- This initial integration includes Mass and Diffusion integrators. libCEED GPU
-  backends can be used without specific MFEM configuration, however it is highly
-  recommended to use the "cuda" build option to minimize memory transfers.
-
-- Both CPU and GPU modes are available as MFEM device backends (ceed-cpu and
-  ceed-cuda), using some of the best performing CPU and GPU backends from
-  libCEED, see the sample runs in examples 1 and 6.
-
-- NOTE: The current default libCEED GPU backend (ceed-cuda) uses atomics and
-  therefore is non-deterministic.
-
-Partial assembly and matrix-free discretizations
-------------------------------------------------
-- The support for matrix-free methods on both CPU and GPU devices based on a
-  partially assembled operator decomposition was extended to include:
-  * DG integrators, (for now only in the Gauss-Lobatto basis), see Example 9,
-  * H(curl) bilinear forms, see Example 3,
-  * vector mass and vector diffusion bilinear integrators,
-  * convection integrator with improved performance,
-  * gradient and vector divergence integrators for Stokes problems,
-  * initial partial assembly mode for NonlinearForms.
-
-- Diagonals of partially assembled operators can now be computed efficiently.
-  See the new methods AssembleDiagonal in BilinearForm, AssembleDiagonalPA in
-  BilinearFormIntegrator and the implementations in fem/bilininteg_*.cpp.
-
-- In many examples, the partial assembly algorithms provide significantly
-  improved performance, particularly in high-order 3D runs on GPUs.
-
-Meshing improvements
---------------------
-- The algorithms for mesh element numbering were changed to have significantly
-  better caching and parallel partitioning properties. Both initial (see e.g.
-  Mesh::GetHilbertElementOrdering) and ordering after uniform refinement were
-  improved. NOTE: new ordering can have a round-off effect on solver results.
-
-- Added support for non-conforming AMR on both prisms and tetrahedra, including
-  coarsening and parallel load balancing. Anisotropic prism refinement is only
-  available in the serial version at the moment.
-
-- The TMOP mesh optimization algorithms were extended to support r-adaptivity.
-  Target matrices can now be constructed either via a given analytical function
-  (e.g. spatial dependence of size, aspect ratio, etc., for each element) or via
-  a (Par)GridFunction specified on the original mesh.
-
-- The TMOP algorithms were also improved to support non-conforming AMR meshes.
-
-- Added support for creating refined versions of periodic meshes, making use of
-  the new L2ElementRestriction class. This class also allows for computing
-  geometric factors on periodic meshes using partial assembly.
-
-Discretization improvements
----------------------------
-- Added support for GSLIB-FindPoints, a general high-order interpolation utility
-  that can robustly evaluate a GridFunction in an arbitrary collection of points
-  in physical space. See INSTALL for details on building MFEM with GSLIB, and
-  miniapps/gslib for examples of how to use this feature.
-
-- Added support for complex-valued finite element operators and fields using a
-  2x2 block structured linear system to mimic complex arithmetic. New classes
-  include: ComplexGridFunction, SesquilinearForm, ComplexLinearForm, and their
-  parallel counterparts.
-
-- Added second order derivatives of NURBS shape functions.
-
-- Added support for serendipity elements of arbitrary order on affinely-mapped
-  square elements. Basis functions for these elements can be visualized using
-  an option in the display-basis miniapp.
-
-- Two integrators related to Stokes problems, (Q grad u, v) and (Q div v, u),
-  where u and the components of v are in H1, were added/modified to support full
-  and partial assembly modes. See the new GradientIntegrator and the updated
-  VectorDivergenceIntegrator classes in fem/bilininteg.hpp, as well as the PA
-  kernels in fem/bilininteg_gradient.cpp and fem/bilininteg_divergence.cpp.
-
-- Added a nonlinear vector valued convection integrator (Q u \cdot grad u, v)
-  where u_i and v_i are in H1. This form occurs e.g. in the Navier-Stokes
-  equations. The integrator supports the partial assembly mode for its
-  action. In full assembly mode we also provide the GetGradient method that
-  computes the linearized version of the integrator.
-
-- Added a new method, MixedBilinearForm::FormRectangularLinearSystem, that can
-  be used to impose boundary conditions on the non-square off-diagonal blocks of
-  a block operator (similar to FormLinearSystem in the square case).
-
-Linear and nonlinear solvers
-----------------------------
-- Added support for Ginkgo, a high-performance linear algebra library for GPU
-  and manycore nodes, with a focus on sparse solution of linear systems. For
-  more details see linalg/ginkgo.hpp and the example code in examples/gingko.
-
-- Added support for HiOp, a lightweight HPC solver for nonlinear optimization
-  problems, see class HiOpNLPOptimizer and the example codes in examples/hiop.
-
-- Added a general interface for specifying and solving nonlinear constrained
-  optimization problems through the new classes OptimizationProblem and
-  OptimizationSolver, see linalg/solver.hpp.
-
-- Added a block ILU(0) preconditioner for DG-type discretizations. Example 9
-  (DG advection) now takes advantage of this for implicit time integration.
-
-- New time integrators: Adams-Bashforth, Adams-Moulton and several integrators
-  for 2nd order ODEs, see the new Example 23.
-
-- Added a LinearSolve(A,X) convenience method to solve dense linear systems. In
-  the trivial cases, i.e., square matrices of size 1 or 2, the system is solved
-  directly, otherwise, LU factorization is employed.
-
-New and updated examples and miniapps
--------------------------------------
-- Added a collection of 7 playful miniapps in miniapps/toys that illustrate the
-  meshing and visualization features of the library in more relaxed settings.
-  The toys include simulations of cellular automata, Rubik's cube, Mandelbrot
-  set, a tool to convert any image to mfem mesh, and more.
-
-- Added 8 new example codes:
-  * Example 22/22p demonstrates the use of the new complex-valued finite element
-    operators by defining and solving a family of time-harmonic PDEs related to
-    damped harmonic oscillators.
-  * Example 23 solves a simple 2D/3D wave equation with the new second order
-    time integrators.
-  * Example 24/24p demonstrates usage of mixed finite element spaces in bilinear
-    forms. Partial assembly is supported in this example.
-  * A version of Example 1 in examples/ginkgo demonstrating the use of the
-    Gingko interface to solve a linear system.
-  * A version of Example 9/9p in examples/hiop demonstrating the nonlinear
-    constrained optimization interface and use of the SLBQP and HiOp solvers.
-
-- Added two new miniapps: Find Points and Field Diff in miniapps/gslib that show
-  how GSLIB-FindPoints can be used to interpolate a (Par) GridFunction in an
-  arbitrary number of physical space points in 2D and 3D. The GridFunction must
-  be in H1 and in the same space as the mesh that is used to find the points.
-
-- Added a simple miniapp, Get Values, that extracts field values at a set of
-  points, from previously saved data via DataCollection classes.
-
-- Several examples and miniapps were updated:
-  * Added device support in Example 3/3p and Example 9/9p.
-  * Example 1/1p and Example 3/3p now use diagonal preconditioning in partial
-    assembly mode.
-  * Example 9/9p now supports implicit time integration, using the new block
-    ILU(0) solvers as preconditioners for the linear system.
-  * The mesh-optimizer and pmesh-optimizer miniapps now include the new
-    r-adaptivity capabilities of TMOP. They were also updated to support mesh
-    optimization on non-conforming AMR meshes.
-  * New options to reorder and partition the mesh and boundary attribute
-    visualization (key 'b') are now available in the mesh-explorer miniapp.
-
-- Collected object files from the miniapps/common directory into a new library,
-  libmfem-common for the convenience of application developers. The new library
-  is now used in several miniapps in the electromagnetic and tools directories.
-
-Improved testing
-----------------
-- Added a large number of unit tests in the tests/unit directory, including
-  several parallel unit tests.
-
-- Added a new directory, tests/scripts, with several shell scripts that perform
-  simple checks on the code including: code styling, documentation formatting,
-  proper use of .gitignore, and preventing the accidental commit of large files.
-
-- It is recommended that developers run the above tests scripts (via the runtest
-  script) before pushing to GitHub. See the README file in tests/scripts.
-
-- The Travis CI settings have been updated to include an initial Checks stage
-  which currently runs the code-style, documentation and gitignore test scripts,
-  as well as a final stage for optional checks/tests which currently runs the
-  branch-history script.
-
-Miscellaneous
--------------
-- Added support for output in the ParaView XML format. Both low-order and
-  high-order Lagrange elements are supported. Output can be in ASCII or binary
-  format. The binary output can be compressed if MFEM is compiled with zlib
-  support (MFEM_USE_ZLIB). See the new ParaViewDataCollection class and the
-  updated Examples 5/5p and 9/9p.
-
-- Upgraded the SUNDIALS interface to utilize SUNDIALS 5.0. This necessitated a
-  complete rework of the interface and requires changes at the application
-  level. Example usage of the new interface can be found in examples/sundials.
-
-- Switched from gzstream to zstr for the implementation of zlib-compressed C++
-  output stream. The build system definition now uses MFEM_USE_ZLIB instead of
-  MFEM_USE_GZSTREAM, but the code interface (e.g. ofgzstream) remains the same.
-
-- Various other simplifications, extensions, and bugfixes in the code.
-
-API changes
------------
-- In the enum classes MemoryType and MemoryClass, "CUDA" was renamed to "DEVICE"
-  which now denotes either "CUDA" or "HIP" depending on the build configuration.
-  In the same enum classes, "CUDA_UVM" was renamed to "MANAGED".
-
-
-Version 4.0, released on May 24, 2019
+Development version, not released yet
 =====================================
 
-Unlike previous MFEM releases, this version requires a C++11 compiler.
-
-GPU support
------------
-- Added initial support for hardware devices, such as GPUs, and programming
-  models, such as CUDA, OCCA, RAJA and OpenMP.
-
-- The GPU/device support is based on MFEM's new backends and kernels working
-  seamlessly with a new lightweight device/host memory manager. The kernels can
-  be implemented either in OCCA, or as a simple wrapper around for-loops, which
-  can then be dispatched to RAJA and native backends. See the files forall.hpp
-  and mem_manager.hpp in the general/ directory for more details.
-
-- Several of the MFEM example codes (ex1, ex1p, ex6, and ex6p) can now take
-  advantage of GPU acceleration with the backend selectable at runtime. Many of
-  the linear algebra and finite element operations (e.g. partially assembled
-  bilinear forms) have been extended to take advantage of kernel acceleration by
-  simply replacing loops with the MFEM_FORALL() macro.
-
-- In addition to native CUDA kernels, the library currently supports OCCA, RAJA
-  and OpenMP kernels, which could be mixed and matched in different parts of the
-  same application. We plan on adding support for more programming models and
-  devices in the future, without the need for significant modifications in user
-  code. The list of current backends is: "occa-cuda", "raja-cuda", "cuda",
-  "occa-omp", "raja-omp", "omp", "occa-cpu", "raja-cpu", and "cpu".
-
-- GPU-related limitations:
-  * Hypre preconditioners are not yet available in GPU mode, and in particular
-    hypre must be built in CPU mode.
-  * Only constant coefficients are currently supported on GPUs.
-  * Optimized element assembly, and matrix-free bilinear forms are not
-    implemented yet. Element batching is currently ignored.
-  * In device mode, full assembly is performed on the host (but the matvec
-    action is performed on the device).
-  * Partial assembly kernels are not implemented yet for simplices.
-
-Discretization improvements
----------------------------
-- Partial assembled finite element operators are now available in the core
-  library, based on the new classes PABilinearFormExtension, ElementRestriction,
-  DofToQuad and GeometricFactors (associated with the classes BilinearForm,
-  FiniteElementSpace, FiniteElement and Mesh, respectively). The kernels for
-  partial assembled Setup/Assembly and Action/Mult are implemented in the
-  BilinearFormIntegrator methods AssemblePA and AddMultPA.
-
-- Added support for a general "low-order refined"-to-"high-order" transfer of
-  GridFunction data from a "low-order refined" (LOR) space defined on a refined
-  mesh to a "high-order" (HO) finite element space defined on a coarse mesh. See
-  the new classes InterpolationGridTransfer and L2ProjectionGridTransfer and the
-  new LOR Transfer miniapp: miniapps/tools/lor-transfer.cpp.
-
-- Added element flux, and flux energy computation in class ElasticityIntegrator,
-  allowing for the use of Zienkiewicz-Zhu type error estimators with the
-  integrator. For an illustration of this addition, see the new Example 21.
-
-- Added support for derefinement of vector (RT + ND) spaces.
-
-- Added a variety of coefficients which are sums or products of existing
-  coefficients as well as grid function coefficients which return the
-  divergence, gradient, or curl of their GridFunctions.
-
-Support for wedge elements and meshes with mixed element types
---------------------------------------------------------------
-- Added support for wedge-shaped mesh elements of arbitrary order (with Geometry
-  type PRISM) which have two triangular faces and three quadrilateral faces.
-  Several examples of such meshes can be found in the data/ directory.
-
-- Added support for mixed meshes containing triangles and quadrilaterals in 2D
-  or tetrahedra, wedges, and hexahedra in 3D. This includes support for uniform
-  refinement of such meshes. Several examples of such meshes can be found in the
-  data/ directory.
-
-- Added H1 and L2 finite elements of arbitrary order for Wedge elements.
-
-- Added support for reading and writing linear and quadratic meshes containing
-  wedge elements in VTK mesh format. Several examples of such meshes can be
-  found in the data/ directory.
-
-Other meshing improvements
---------------------------
-- Improved the uniform refinement of tetrahedral meshes (also part of the
-  uniform refinement of mixed 3D meshes). The previous refinement algorithm is
-  still available as an option in Mesh::UniformRefinement. Both can be used in
-  the updated Mesh Explorer miniapp.
-
-- The local tetrahedral mesh refinement algorithm in serial and in parallel now
-  follows precisely the paper:
-
-     D. Arnold, A. Mukherjee, and L. Pouly, "Locally Adapted Tetrahedral Meshes
-     Using Bisection", SIAM J. Sci. Comput. 22 (2000), 431–448.
-
-  This guarantees that the shape regularity of the elements will be preserved
-  under refinement.
-
-- The TMOP mesh optimization algorithms were extended to support user-defined
-  space-dependent limiting terms. Improved the TMOP objective functions by more
-  accurate normalization of the different terms.
-
-- Added support for parallel communication groups on non-conforming meshes.
-
-- Improved parallel partitioning of non-conforming meshes. If the coarse mesh
-  elements are ordered as a sequence of face-neighbors, the parallel partitions
-  are now guaranteed to be continuous. To that end, inline quadrilateral and
-  hexahedral meshes are now by default ordered along a space-filling curve.
-
-- A boundary in a NURBS mesh can now be connected with another boundary. Such a
-  periodic NURBS mesh is a simple way to impose periodic boundary conditions.
-
-- Added support for reading linear and quadratic 2D quadrilateral and triangular
-  Cubit meshes.
-
-New and updated examples and miniapps
--------------------------------------
-- Added a new meshing miniapp, Toroid, which can produce a variety of torus
-  shaped meshes by twisting a stack of wedges or hexahedra.
-
-- Added a new meshing miniapp, Extruder, that demonstrates the capability to
-  produce 3D meshes by extruding 2D meshes.
-
-- Added a simple miniapp, LOR Transfer, for visualizing the actions of the
-  transfer operators between a high-order and a low-order refined spaces.
-
-- Added a new example, Example 20/20p, that solves a system of 1D ODEs derived
-  from a Hamiltonian. The example demonstrates the use of the variable order,
-  symplectic integration algorithm implemented in class SIAVSolver.
-
-- Added a new example, Example 21/21p, that illustrates the use of AMR to solve
-  a linear elasticity problem. This is an extension of Example 2/2p.
-
-New and improved solvers and preconditioners
---------------------------------------------
-- Added support for parallel ILU preconditioning via hypre's Euclid solver.
-
-- Added support for STRUMPACK v3 with a small API change in the class
-  STRUMPACKSolver, see "API changes" below.
-
-Miscellaneous
--------------
-- Added unit tests based on the Catch++ library in the test/ directory.
-
-- Renamed the option MFEM_USE_OPENMP to MFEM_USE_LEGACY_OPENMP. This legacy
-  option is deprecated and planned for removal in a future release. The original
-  option name, MFEM_USE_OPENMP, is now used to enable the new OpenMP backends in
-  the new kernels.
-
-- In SparseMatrix added the option to perform MultTranspose() by matvec with
-  computed and stored transpose matrix. This is required for deterministic
-  results when using devices such as CUDA and OpenMP.
-
-- Altered the way FGMRES counts its iterations so that it matches GMRES.
-
-- Various other simplifications, extensions, and bugfixes in the code.
-
-- Construct abstract parallel rectangular truedof-to-truedof operators via
-  Operator::FormDiscreteOperator().
-
-API changes
------------
-- In multiple places, use Geometry::Type instead of int, where appropriate.
-- In multiple places, use Element::Type instead of int, where appropriate.
-- The Mesh methods GetElementBaseGeometry and GetBdrElementBaseGeometry no
-  longer have a default value for their parameter, they only work with an
-  explicitly given index.
-- In class Mesh, added methods useful for queries regarding the types of
-  elements present in the mesh: HasGeometry, GetNumGeometries, GetGeometries,
-  and class Mesh::GeometryList.
-- The struct CoarseFineTransformations (returned by the Mesh method
-  GetRefinementTransforms) now stores the embedding matrices separately for each
-  Geometry::Type.
-- In class ParMesh, replaced the method GroupNFaces with two new methods:
-  GroupNTriangles and GroupNQuadrilaterals. Also, replaced GroupFace with two
-  methods: GroupTriangle and GroupQuadrilateral.
-- In class ParMesh, made the two RefineGroups methods protected.
-- Removed the virtual method Element::GetRefinementFlag, it is only used by the
-  derived class Tetrahedron.
-- Added new methods: Array::CopyTo, Tetrahedron::Init.
-- In class STRUMPACKSolver, the method SetMC64Job() was replaced by the new
-  methods: DisableMatching(), EnableMatching(), and EnableParallelMatching().
-
-
-Version 3.4, released on May 29, 2018
-=====================================
-
-More general and efficient mesh adaptivity
-------------------------------------------
-- Added support for PUMI, the Parallel Unstructured Mesh Infrastructure from
-  https://scorec.rpi.edu/pumi. PUMI is an unstructured, distributed mesh data
-  management system that is capable of handling general non-manifold models and
-  effectively supports automated adaptive analysis. PUMI enables for the first
-  time support for parallel unstructured modifications of MFEM meshes.
-
-- Significantly reduced MPI communication in the construction of the parallel
-  prolongation matrix in ParFiniteElementSpace, for much improved parallel
-  scaling of non-conforming AMR on hundreds of thousands of MPI tasks. The
-  memory footprint of the ParNCMesh class has also been reduced.
-
-- In FiniteElementSpace, the fully assembled refinement matrix is now replaced
-  by default by a specialized refinement operator. The operator option is both
-  faster and more memory efficient than using the fully assembled matrix. The
-  old approach is still available and can be enabled, if needed, using the new
-  method FiniteElementSpace::SetUpdateOperatorType().
-
-Discretization improvements
----------------------------
-- Added support for a general "high-order"-to-"low-order refined" transfer of
-  GridFunction and true-dof data from a "high-order" finite element space
-  defined on a coarse mesh, to a "low-order refined" space defined on a refined
-  mesh. The new methods, GetTransferOperator and GetTrueTransferOperator in the
-  FiniteElementSpace classes, work in both serial and parallel and support
-  matrix-based as well as matrix-free transfer operator representations. They
-  use a new method, GetTransferMatrix, in the FiniteElement class similar to
-  GetLocalInterpolation, that allows the coarse FiniteElement to be different
-  from the fine FiniteElement.
-
-- Added class ComplexOperator, that implements the action of a complex operator
-  through the equivalent 2x2 real formulation. Both symmetric and antisymmetric
-  block structures are supported.
-
-- Added classes for general block nonlinear finite element operators (deriving
-  from BlockNonlinearForm and ParBlockNonlinearForm) enabling solution of
-  nonlinear systems with multiple unknowns in different function spaces. Such
-  operators have assemble-based action and also support assembly of the gradient
-  operator to enable inversion with Newton iteration.
-
-- Added variable order NURBS: for each space each knot vector in the mesh can
-  have a different order. The order information is now part of the finite
-  element space header in the NURBS mesh output, so NURBS meshes in the old
-  format need to be updated.
-
-- In the classes NonlinearForm and ParNonlinearForm, added support for
-  non-conforming AMR meshes; see also the "API changes" section.
-
-- New specialized time integrators: symplectic integrators of orders 1-4 for
-  systems of first order ODEs derived from a Hamiltonian and generalized-alpha
-  ODE solver for the filtered Navier–Stokes equations with stabilization. See
-  classes SIASolver and GeneralizedAlphaSolver in linalg/ode.hpp.
-
-- Inherit finite element classes from the new base class TensorBasisElement,
-  whenever the basis can be represented by a tensor product of 1D bases.
-
-- Added support for elimination of boundary conditions in block matrices.
-
-New and updated examples and miniapps
--------------------------------------
-- Added a new serial and parallel example (ex19) that solves the quasi-static
-  incompressible hyperelastic equations. The example demonstrates the use of
-  block nonlinear forms as well as custom block preconditioners.
-
-- Added a new serial example (ex23) to demonstrate the use of second order
-  time integration to solve the wave equation.
-
-- Added a new electromagnetics miniapp, Maxwell, for simulating time-domain
-  electromagnetics phenomena as a coupled first order system of equations.
-
-- A simple local refinement option has been added to the mesh-explorer miniapp
-  (menu option 'r', sub-option 'l') that selects elements for refinement based
-  on their spatial location - see the function 'region()' in the source file.
-
-- Added a set of miniapps specifically focused on Isogeometric Analysis (IGA) on
-  NURBS meshes in the miniapps/nurbs directory. Currently the directory contains
-  variable order NURBS versions of examples 1, 1p and 11p.
-
-- Added PUMI versions of examples ex1, ex1p, ex2 and ex6p in a new examples/pumi
-  directory. The new examples demonstrate the PUMI APIs for parallel and serial
-  mesh loading (ex1 and ex1p), applying BCs using classification (ex2), and
-  performing parallel mesh adaptation (ex6p).
-
-- Added two new miniapps related to DataCollection I/O in miniapps/tools:
-  load-dc.cpp can be used to visualize fields saved via DataCollection classes;
-  convert-dc.cpp demonstrates how to convert between MFEM's different concrete
-  DataCollection options.
-
-- Example 10p with its SUNDIALS and PETSc versions have been updated to reflect
-  the change in the behavior of the method ParNonlinearForm::GetLocalGradient()
-  (see the "API changes" section) and now works correctly on non-conforming AMR
-  meshes. Example 10 and its SUNDIALS version have also been updated to support
-  non-conforming ARM meshes.
-
-Miscellaneous
--------------
-- Documented project workflow and provided contribution guidelines in the new
-  top-level file, CONTRIBUTING.md.
-
-- Added (optional) Conduit Mesh Blueprint support of MFEM data for both in-core
-  and I/O use cases. This includes a new ConduitDataCollection that provides
-  json, simple binary, and HDF5-based I/O. Support requires Conduit >= v0.3.1
-  and VisIt >= v2.13.1 will read the new Data Collection outputs.
-
-- Added a new developer tool, config/sample-runs.sh, that extracts the sample
-  runs from all examples and miniapps and runs them. Optionally, it can save the
-  output from the execution to files, allowing comparison between different
-  versions and builds of the library.
-
-- Support for building a shared version of the MFEM library with GNU make.
-
-- Added a build option, MFEM_USE_EXCEPTIONS=YES, to throw an exception instead
-  of calling abort on mfem errors.
-
-- When building with the GnuTLS library, switch to using X.509 certificates for
-  secure socket authentication. Support for the previously used OpenPGP keys has
-  been deprecated in GnuTLS 3.5.x and removed in 3.6.0. For secure communication
-  with the visualization tool GLVis, a new set of certificates can be generated
-  using the latest version of the script 'glvis-keygen.sh' from GLVis.
-
-- Upgraded MFEM to support Axom 0.2.8. Prior versions are no longer supported.
-
-API changes
------------
-- Introduced a new enum, Matrix::DiagonalPolicy, that replaces the integer
-  parameters in many methods that perform elimination of rows and/or columns in
-  matrices. Some examples of such methods are:
-  * class SparseMatrix: EliminateRow(), EliminateCol(), EliminateRowCol(), ...
-  * class BilinearForm: EliminateEssentialBC(), EliminateVDofs(), ...
-  * class StaticCondensation: EliminateReducedTrueDofs()
-  * class BlockMatrix: EliminateRowCol()
-  Calling these methods with an explicitly given (integer) constants, will now
-  generate compilation errors, please use one of the new enum constants instead.
-
-- Modified the virtual method AbstractSparseMatrix::EliminateZeroRows() and its
-  implementations in derived classes, to accept an optional 'threshold'
-  parameter, replacing previously hard-coded threshold values.
-
-- In the classes NonlinearForm and ParNonlinearForm:
-  * The method GetLocalGradient() no longer imposes boundary conditions. The
-    motivation for the change is that, in the case of non-conforming AMR,
-    performing the elimination at the local level is incorrect - it must be
-    applied at the true-dof level.
-  * The method SetEssentialVDofs() is now deprecated.
-
-
-Version 3.3.2, released on Nov 10, 2017
-=======================================
-
-High-order mesh optimization
-----------------------------
-- Added support for mesh optimization via node-movement based on the Target-
-  Matrix Optimization Paradigm (TMOP) developed by P.Knupp et al. A variety of
-  mesh quality metrics, with their first and second derivatives have been
-  implemented. The combination of targets & quality metrics is used to optimize
-  the physical node positions, i.e., they must be as close as possible to the
-  shape, size and/or alignment of their targets. The optimization of arbitrary
-  high-order meshes in 2D, 3D, serial and parallel is supported.
-
-- The new Mesh Optimizer miniapp can be used to perform mesh optimization with
-  TMOP in serial and parallel versions. The miniapp also demonstrates the use of
-  nonlinear operators and their coupling to Newton methods for solving
-  minimization problems.
-
-New and improved solvers and preconditioners
---------------------------------------------
-- MFEM is now included in the xSDK project, the Extreme-scale Scientific
-  Software Development Kit, as of xSDK-0.3.0. Various changes were made to
-  comply with xSDK's community policies, https://xsdk.info/policies, including:
-  xSDK-specific options in CMake, support for user-provided MPI communicators,
-  runtime API for version number, and the ability to disable/redirect output.
-  For more details, see general/globals.hpp and in particular the mfem::err and
-  mfem::out streams replacing std::err and std::out respectively.
-
-- Added (optional) support for the STRUMPACK parallel sparse direct solver and
-  preconditioner. STRUMPACK uses Hierarchically Semi-Separable (HSS) compression
-  in a fully algebraic manner, with interface similar to SuperLU_DIST. See
-  http://portal.nersc.gov/project/sparse/strumpack for more details.
-
-- Added a block lower triangular preconditioner based (only) on the actions of
-  each block, see class BlockLowerTriangularPreconditioner.
-
-- Added an optional operator in LOBPCG to projects vectors onto a desired
-  subspace (e.g. divergence-free). Other small changes in LOBPCG include the
-  ability to set the starting vectors and support for relative tolerance.
-
-- The Newton solver supports an optional scaling factor, that can limit the
-  increment in the Newton step, see e.g. the Mesh Optimizer miniapp.
-
-- Updated MFEM integration to support the new SUNDIALS 3.0.0 interface.
-
-New and updated examples and miniapps
--------------------------------------
-- Added a new serial and parallel example (ex18) that solves the transient Euler
-  equations on a periodic domain with explicit time integrators. In the process
-  extended the NonlinearForm class to allow for integrals over faces and
-  exchanging face-neighbor data in parallel.
-
-- Added a new meshing miniapp, Shaper, that can be used to resolve complicated
-  material interfaces by mesh refinement, e.g. as a tool for initial mesh
-  generation from prescribed "material()" function.  Both conforming and
-  non-conforming (isotropic and anisotropic) refinements are supported.
-
-- Added a new meshing miniapp, Mesh Optimizer, that demonstrates the use of TMOP
-  for mesh optimization (serial and parallel version.)
-
-- Added SUNDIALS version of Example 16/16p.
-
-Discretization improvements
----------------------------
-- Added a FindPoints method of the Mesh and ParMesh classes that returns the
-  elements that contain a given set of points, together with the coordinates of
-  the points in the reference space of the corresponding element.  In parallel,
-  if a point is shared by multiple processors, only one of them will mark that
-  point as found. Note that the current implementation of this method is not
-  optimal and/or 100% reliable. See the mesh-explorer miniapp for an example.
-
-- Added a new class InverseElementTransformation, that supports a number of
-  algorithms for inversion of general ElementTransformations. This class can be
-  used as a more flexible and extensible alternative to ElementTransformation's
-  TransformBack method. It is also used in the FindPoints methods as a tunable
-  and customizable inversion algorithm.
-
-- Memory optimizations in the NCMesh class, which now uses 50% less memory than
-  before. The average cost of an element in a uniformly refined mesh (including
-  the refinement hierarchy, but excluding the temporary face_list and edge_list)
+- Memory optimizations in the NCMesh class, which now uses 50% less memory.
+  The average cost of an NC element in a uniformly refined mesh (including the
+  refinement hierarchy, but excluding the temporary face_list and edge_list)
   is now only about 290 bytes. This also makes the class faster.
 
-- Added the ability to integrate delta functions on the right-hand side (by
-  sampling the test function at the center of the delta coefficient). Currently
-  this is supported in the DomainLFIntegrator, VectorDomainLFIntegrator and
-  VectorFEDomainLFIntegrator classes.
-
-- Added five new linear interpolators in fem/bilininteg.cpp to compute products
-  of scalar and vector fields or products with arbitrary coefficients.
-
-- Added matrix coefficient support to CurlCurlIntegrator.
-
-- Extend the method NodalFiniteElement::Project for VectorCoefficient to work
-  with arbitrary number of vector components.
-
-Miscellaneous
--------------
-- Added a .gitignore file that ignores all files erased by "make distclean",
-  i.e. the files that can be generated from the source but we don't want to
-  track in the repository, as well as a few platform-specific files.
-
-- Added Linux, Mac and Windows CI testing on GitHub with Travis CI and Appveyor.
-
-- Added a new macro, MFEM_VERSION, defined as a single integer of the form
-  (major*100 + minor)*100 + patch. The convention is that an even number
-  (i.e. even patch number) denotes a "release" version, while an odd number
-  denotes a "development" version. See config/config.hpp.in.
-
-- Added an option for building in parallel without a METIS dependency. This is
-  used for example the Laghos miniapp, https://github.com/CEED/Laghos.
-
-- Modified the installation layout: all headers, except the master headers
-  (mfem.hpp and mfem-performance.hpp), are installed in <PREFIX>/include/mfem;
-  the master headers are installed in both <PREFIX>/include/mfem and in
-  <PREFIX>/include. The mfem configuration and testing makefiles (config.mk and
-  test.mk) are installed in <PREFIX>/share/mfem, instead of <PREFIX>.
-
-- Add three more options for MFEM_TIMER_TYPE.
-
-- Support independent number of digits for cycle and rank in DataCollection.
-
-- Converted Sidre usage from "asctoolkit" to "axom" namespace.
-
-- Various small fixes and styling updates.
-
-API changes
------------
-- The methods GetCoeff of VectorArrayCoefficient and MatrixArrayCoefficient now
-  return a pointer to Coefficient (instead of reference). Note that NULL pointer
-  is a valid entry for these two classes - it is treated as the zero function.
-
-- When building with PETSc, the required PETSc version is now 3.8.0. Newer
-  versions may work too, as long as there are no interface changes in PETSc.
-
-- The class GeometryRefiner now uses the enum in Quadrature1D for its type
-  specification. In particular, this will affect older versions of GLVis. A
-  simple upgrade to the latest version of GLVis should resolve this issue.
+- Add a block lower triangular preconditioner in using a matrix-free
+  implementation, see class BlockLowerTriangularPreconditioner.

-### Code Overview
-
-#### Source code structure:
-
-The MFEM library uses object-oriented design principles which reflect, in code,
-the independent mathematical concepts of meshing, linear algebra and finite
-element spaces and operators.
-
-The MFEM source code has the following structure:

-
-#### Main directories and classes
-
-The main directories are `fem/`, `mesh/` and `linalg/` containing the C++
-classes implementing the finite element, mesh and linear algebra concepts
-respectively.
-
-- The main mesh classes are:
-  + [`Mesh`](http://mfem.github.io/doxygen/html/classmfem_1_1Mesh.html)
-  + [`NCMesh`](http://mfem.github.io/doxygen/html/classmfem_1_1NCMesh.html)
-  + [`Element`](http://mfem.github.io/doxygen/html/classmfem_1_1Element.html)
-  + [`ElementTransformation`](http://mfem.github.io/doxygen/html/classmfem_1_1ElementTransformation.html)
-
-- The main finite element classes are:
-  + [`FiniteElement`](http://mfem.github.io/doxygen/html/classmfem_1_1FiniteElement.html)
-  + [`FiniteElementCollection`](http://mfem.github.io/doxygen/html/classmfem_1_1FiniteElement.html)
-  + [`FiniteElementSpace`](http://mfem.github.io/doxygen/html/classmfem_1_1FiniteElementSpace.html)
-  + [`GridFunction`](http://mfem.github.io/doxygen/html/classmfem_1_1GridFunction.html)
-  + [`BilinearFormIntegrator`](http://mfem.github.io/doxygen/html/classmfem_1_1BilinearFormIntegrator.html) and [`LinearFormIntegrator`](http://mfem.github.io/doxygen/html/classmfem_1_1LinearFormIntegrator.html)
-  + [`LinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1LinearFormIntegrator.html), [`BilinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1BilinearForm.html) and [`MixedBilinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1MixedBilinearForm.html)
-
-- The main linear algebra classes and sources are
-  + [`Operator`](http://mfem.github.io/doxygen/html/classmfem_1_1Operator.html) and [`BilinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1BilinearForm.html)
-  + [`Vector`](http://mfem.github.io/doxygen/html/classmfem_1_1BilinearForm.html) and [`LinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1LinearForm.html)
-  + [`DenseMatrix`](http://mfem.github.io/doxygen/html/classmfem_1_1DenseMatrix.html) and [`SparseMatrix`](http://mfem.github.io/doxygen/html/classmfem_1_1SparseMatrix.html)
-  + Sparse [smoothers](http://mfem.github.io/doxygen/html/sparsesmoothers_8hpp.html) and linear [solvers](http://mfem.github.io/doxygen/html/solvers_8hpp.html)
-
-#### Parallel implementation
-
-Parallel MPI objects in MFEM inherit their serial counterparts, so a parallel
-mesh for example is just a serial mesh on each task plus the information on
-shared geometric entities between different tasks. The parallel source files
-have a `p` prefix, e.g. `pmesh.cpp` vs. the serial `mesh.cpp`.
-
-- The main parallel classes are
-  + [`ParMesh`](http://mfem.github.io/doxygen/html/solvers_8hpp.html)
-  + [`ParNCMesh`](http://mfem.github.io/doxygen/html/classmfem_1_1ParMesh.html)
-  + [`ParFiniteElementSpace`](http://mfem.github.io/doxygen/html/classmfem_1_1ParFiniteElementSpace.html)
-  + [`ParGridFunction`](http://mfem.github.io/doxygen/html/classmfem_1_1ParGridFunction.html)
-  + [`ParBilinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1ParBilinearForm.html) and [`ParLinearForm`](http://mfem.github.io/doxygen/html/classmfem_1_1ParLinearForm.html)
-  + [`HypreParMatrix`](http://mfem.github.io/doxygen/html/classmfem_1_1HypreParMatrix.html) and [`HypreParVector`](http://mfem.github.io/doxygen/html/classmfem_1_1HypreParVector.html)
-  + [`HypreSolver`](http://mfem.github.io/doxygen/html/classmfem_1_1HypreSolver.html) and other [hypre classes](http://mfem.github.io/doxygen/html/hypre_8hpp.html)
-
-#### GPU and general device support
-
-GPU and multi-core CPU support is based on device kernels supporting different
-backends (CUDA, OCCA, RAJA, OpenMP, etc.) and an internal lightweight
-device/host memory manager.
-
-- The main device-relevant classes and sources are:
-  + [`Device`](http://mfem.github.io/doxygen/html/device_8hpp.html)
-  + [`MemoryManager`](http://mfem.github.io/doxygen/html/mem_manager_8hpp.html)
-  + the [`MFEM_FORALL`](http://mfem.github.io/doxygen/html/forall_8hpp.html) macro
-  + the [`cuda.hpp`](http://mfem.github.io/doxygen/html/cuda_8hpp.html) and [`occa.hpp`](http://mfem.github.io/doxygen/html/occa_8hpp.html) files
-
-#### Utilities, building and documentation
-- The `general/` directory contains C++ classes that serve as utilities for
-  communication, error handling, arrays, (Boolean) tables, timing, etc.
-- The `config/` directory contains build-related files, both for the plain
-  Makefile and the CMake build options.
-- The `doc/` directory contains configuration for the Doxygen code documentation
-  that can either be built locally or browsed online at
-  http://mfem.github.io/doxygen/html/index.html.
-
-#### Examples and tests
-- `examples` and `miniapps` respectively gather simple and more fully-featured
-  demonstrations of the usage on MFEM. They both rely on `data/` for the
-  collection of meshes.
-- The `tests/` directory contains a unit test suite and will later contain more
-  tests that run example codes.
-
-See also the [code overview](http://mfem.org/code-overview/) section on the MFEM
-website.
-
-## GitHub Workflow
-
-The MFEM GitHub organization: https://github.com/mfem, is the main developer hub
-for the MFEM project.
-
-If you plan to make contributions or would like to stay up-to-date with changes
-in the code, *we strongly encourage you to [join the MFEM organization](#mfem-organization)*.
-
-This will simplify the workflow (by providing you additional permissions), and
-will allow us to reach you directly with project announcements.
-
-
-### MFEM Organization
-
-#### Getting started (GitHub)
-Before you can start, you need a GitHub account, here are a few suggestions:
-  + Create the account at: [github.com/join](https://github.com/join).
-  + For easy identification, please add your full name and maybe a picture of you at:
-    https://github.com/settings/profile.
-  + To receive notification, set a primary email at: https://github.com/settings/emails.
-  + For password-less pull/push over SSH, add your SSH keys at: https://github.com/settings/keys.
-
-#### Joining
-- [Contact us](#contact-information) for an invitation to join the MFEM GitHub
-  organization. You will receive an invitation email, which you can directly accept.
-  Alternatively, *after logging into GitHub*, you can accept the invitation at
-  the top of https://github.com/mfem.
-- Consider making your membership public by going to https://github.com/orgs/mfem/people
-  and clicking on the organization visibility drop box next to your name.
-- Project discussions and announcements will be posted at
-  https://github.com/orgs/mfem/teams/everyone.
-
-#### Structure
-- The MFEM source code is in the [mfem](https://github.com/mfem/mfem)
-  repository.
-- The website and corresponding documentation are in the
-  [web](https://github.com/mfem/web) repository.
-- The [PyMFEM](https://github.com/mfem/PyMFEM) repository contains a Python
-  wrapper for MFEM.
-- The [data](https://github.com/mfem/data) repository contains additional
-  (large) datafiles for MFEM.
-
-
-### New Feature Development
-
-- A new feature should be important enough that at least one person, the
-  author, is willing to work on it and be its champion.
-
-- The author creates a branch for the new feature (with suffix `-dev`), off
-  the `master` branch, or another existing feature branch, for example:
-
-  ```
-  # Clone assuming you have setup your ssh keys on GitHub:
-  git clone git@github.com:mfem/mfem.git
-
-  # Alternatively, clone using the "https" protocol:
-  git clone https://github.com/mfem/mfem.git
-
-  # Create a new feature branch starting from "master":
-  git checkout master
-  git pull
-  git checkout -b feature-dev
-
-  # Work on "feature-dev", add local commits
-  # ...
-
-  # (One time only) push the branch to github and setup your local
-  # branch to track the github branch (for "git pull"):
-  git push -u origin feature-dev
-
-  ```
-
-- **We prefer that you create the new feature branch inside the MFEM organization
-  as opposed to in a fork.** This allows everyone in the community to collaborate
-  in one central place.
-
-  - If you prefer to work in your fork, please [enable upstream edits](https://help.github.com/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork/).
-
-  - Never use the `next` branch to start a new feature branch!
-
-- The typical feature branch name is `new-feature-dev`, e.g. `pumi-dev`. While
-  not frequent in MFEM, other suffixes are possible, e.g. `-fix`, `-doc`, etc.
-
-
-### Developer Guidelines
-
-- *Keep the code lean and as simple as possible*
-  - Well-designed simple code is frequently more general and powerful.
-  - Lean code base is easier to understand by new collaborators.
-  - New features should be added only if they are necessary or generally useful.
-  - Introduction of language constructions not currently used in MFEM should be
-    justified and generally avoided (to maintain portability to various systems
-    and compilers, including early access hardware).
-  - We prefer basic C++ and the C++03 standard, to keep the code readable by
-    a large audience and to make sure it compiles anywhere.
-
-- *Keep the code general and reasonably efficient*
-  - The main goal is fast prototyping for research and application development.
-  - When in doubt, generality wins over efficiency.
-  - Respect the needs of different users (current and/or future).
-
-- *Keep things separate and logically organized*
-  - General usage features go in MFEM (implemented in as much generality as
-    possible), non-general features go into external apps.
-  - Inside MFEM, compartmentalize between linalg, fem, mesh, GLVis, etc.
-  - Contributions that are project-specific or have external dependencies are
-    allowed (if they are of broader interest), but should be `#ifdef`-ed and not
-    change the code by default.
-
-- Code specifics
-  - All significant new classes, methods and functions have Doxygen-style
-    documentation in source comments.
-  - Consistent code styling is enforced with `make style` in the top-level
-    directory. This requires [Artistic Style](http://astyle.sourceforge.net) (we
-    specifically use version 2.05.1). See also the file `config/mfem.astylerc`.
-  - Use `mfem::out` and `mfem::err` instead of `std::cout` and `std::cerr` in
-    internal library code. (You can use `std` in examples and miniapps.)
-  - When manually resolving conflicts during a merge, make sure to mention the
-    conflicted files in the commit message.
-
-### Pull Requests
-
-- When your branch is ready for other developers to review / comment on
-  the code, create a pull request towards `mfem:master`.
-
-- Pull request typically have titles like:
-
-     `Description [new-feature-dev]`
-
-  for example:
-
-     `Parallel Unstructured Mesh Infrastructure (PUMI) integration [pumi-dev]`
-
-  Note the branch name suffix (in square brackets).
-
-- Titles may contain a prefix in square brackets to emphasize the type of PR.
-  Common choices are: `[DON'T MERGE]`, `[WIP]` and `[DISCUSS]`, for example:
-
-     `[DISCUSS] Hybridized DG [hdg-dev]`
-
-- If the PR is still a work in progress, add the `WIP` label to it and
-  optionally the `[WIP]` prefix in the title.
-
-- Add a description, appropriate labels and assign yourself to the PR. The MFEM
-  team will add reviewers as appropriate.
-
-- List outstanding TODO items in the description, see PR #222 for an example.
-
-- When your contribution is fully working and ready to be reviewed, add
-  the `ready-for-review` label.
-
-- PRs are treated similarly to journal submission with an "editor" assigning
-  two reviewers to evaluate the changes. The reviewers have 3 weeks to evaluate
-  the PR and work with the author to implement improvements and fix issues.
-
-- After approval, the PR is [tested](#masternext-workflow) for a week with
-  other approved PRs in the `mfem:next` branch.
-
-- Consider manually running the tests in `tests/scripts` before merging in
-  `mfem:next`, see the [README](tests/scripts/README) file in that directory
-  for more details.
-
-- Track the Travis CI and Appveyor [continuous integration](#automated-testing)
-  builds at the end of the PR. These should generally run clean, so address any
-  errors as soon as possible. Please ask if you are unsure how to do that.
-
-- Note that some tests, such as the `branch-history` check in Travis are
-  safeguards that are allowed to fail in certain cases.
-
-- Other tests, such as the `code-style`, `documentation` and `gitignore`
-  checks in Travis enforce MFEM-specific rules which are explained in the
-  error messages and the `tests/scripts` directory.
-
-- If triggered, track the status of the LLNL GitLab tests. If failing, ask
-  one of the _LLNL developers_ for details.
-

-### Master/Next Workflow
-
-MFEM uses a `master`/`next`-branch workflow as described below:
-
-- The `master` branch should always be of release quality and changes should not
-  be merged until they have been fully tested. This branch is protected, and
-  changes can only be made through pull requests.
-
-- After approval, a pull request is merged manually (by MFEM developers) in the
-  `next` branch for testing and the `in-next` label is added to the PR.
-  This can be done as follows:
-
-  ```
-  # Pull the latest version of the "feature-dev" branch
-  git checkout feature-dev
-  git pull
-
-  # Pull the latest version of the "next" branch
-  git checkout next
-  git pull
-
-  # Merge "feature-dev" into "next", resolving conflicts, if necessary.
-  # Use the "--no-ff" flag to create a new commit with merge message.
-  git merge --no-ff feature-dev
-
-  # Push the "next" branch to the server
-  git push
-  ```
-
-- After a week of testing in `next` (excluding bugfixes), both on GitHub, as
-  well as [internally](#tests-at-llnl) at LLNL, the original PR is merged into
-  `master` (provided there are no issues).
-
-- After the merge, the feature branch is deleted (unless it is a long-term
-  project with periodic PRs).
-
-- The `next` branch is used just for integrated testing of all PRs approved for
-  merging into `master` to verify that each works individually and that all of
-  them work as a group. This branch can be discarded at any time, though we
-  typically do that only at the end of a [release cycle](#releases).
-
-
-### Releases
-
-- Releases are just tags in the `master` branch, e.g. https://github.com/mfem/mfem/releases/tag/v3.3.2,
-  and have a version that ends in an even "patch" number, e.g. `v3.2.2` or
-  `v3.4` (by convention `v3.4` is the same as `v3.4.0`.)  Between releases, the
-  version ends in an odd "patch" number, e.g. `v3.3.3`.
-
-- We use [milestones](https://github.com/mfem/mfem/milestones) to coordinate the
-  work on different PRs toward a release, see for example the
-  [v3.3.2 release](https://github.com/mfem/mfem/milestone/1?closed=1).
-
-- After a release is complete, the `next` branch is recreated, e.g. as follows
-  (replace `3.3.2` with current release):
-  - Rename the current `next` branch to `next-pre-v3.3.2`.
-  - Create a new `next` branch starting from the `v3.3.2` release.
-  - Local copies of `next` can then be updated with `git fetch origin next && git checkout -B next origin/next`.
-
-### Release Checklist
-
-- [ ] Update the MFEM version in the following files:
-    - [ ] `CHANGELOG`
-    - [ ] `makefile`
-    - [ ] `CMakeLists.txt`
-    - [ ] `doc/CodeDocumentation.conf.in`
-- [ ] Check that version requirements for each of MFEM's dependencies are documented in `INSTALL` and up-to-date
-- [ ] Check that continuous integration server configurations reflect the dependency version requirements of the new release
-    - [ ] `.travis.yml`
-    - [ ] `.appveyor.yml`
-- [ ] (LLNL only) Make sure all `README.html` files in the source repo are up to date.
-- [ ] Tag the repository:
-
-  ```
-  git tag -a v3.1 -m "Official release v3.1"
-  git push origin v3.1
-  ```
-- [ ] Create the release tarball and push to `mfem/releases`.
-- [ ] Recreate the `next` branch as described in previous section.
-- [ ] Update and push documentation  to `mfem/doxygen`.
-- [ ] Update URL shortlinks:
-    - [ ] Create a shortlink at [http://bit.ly/](http://bit.ly/) for the release tarball, e.g. http://mfem.github.io/releases/mfem-3.1.tgz.
-    - [ ] (LLNL only) Add and commit the new shortlink in the `links` and `links-mfem` files of the internal `mfem/downloads` repo.
-    - [ ] Add the new shortlinks to the MFEM packages in `spack`, `homebrew/science`, `VisIt`, etc.
-- [ ] Update website in `mfem/web` repo:
-    - Update version and shortlinks in `src/index.md` and `src/download.md`.
-    -  Use [cloc-1.62.pl](http://cloc.sourceforge.net/) and `ls -lh` to estimate the SLOC and the tarball size in `src/download.md`.
-
-
-## LLNL Workflow
-
-### Mirroring on Bitbucket
-
-- The GitHub `master` and `next` branches are mirrored to the LLNL institutional
-  Bitbucket repository as `gh-master` and `gh-next`.
-
-- `gh-master` is merged into LLNL's internal `master` through pull requests; write
-  permissions to `master` are restricted to ensure this is the only way in which it
-  gets updated.
-
-- We never push directly from LLNL to GitHub.
-
-- Versions of the code on LLNL's internal server, from most to least stable:
-  - MFEM official release on mfem.org -- Most stable, tested in many apps.
-  - `mfem:master` -- Recent development version, guaranteed to work.
-  - `mfem:gh-master` -- Stable development version, passed testing, you can use
-     it to build your code between releases.
-  - `mfem:gh-next` -- Bleeding-edge development version, may be broken, use at
-     your own risk.
-
-### Mirroring on GitLab
-
-- MFEM repository is also mirrored on the LLNL GitLab instance, in a
-  semi-automated manner.
-
-- This instance is meant to complete CI testing with tests on Livermore
-  Computing systems. Gitlab pipeline status is reported in the corresponding
-  GitHub pull request.
-
-- No change can be made on this instance.
-
-## Automated Testing
-
-MFEM has several levels of automated testing running on GitHub, as well as on
-local Mac and Linux workstations, and Livermore Computing clusters at LLNL.
-
-### Linux and Mac smoke tests
-We use Travis CI to drive the default tests on the `master` and `next`
-branches. See the `.travis` file and the logs at
-[https://travis-ci.org/mfem/mfem](https://travis-ci.org/mfem/mfem).
-
-Testing using Travis CI should be kept lightweight, as there is a 50 minute time
-constraint on jobs. Two virtual machines are configured - Mac (OS X) and Linux.
-
-- Tests on the `master` branch are triggered whenever a PR is issued on this branch.
-- Tests on the `next` branch are currently scheduled to run each night.
-
-### Windows smoke test
-We use Appveyor to test building with the MS Visual C++ compiler in a Windows
-environment, as well as to test the CMake build. See the `.appveyor` file and the
-build logs at
-[https://ci.appveyor.com/project/mfem/mfem](https://ci.appveyor.com/project/mfem/mfem).
-
-CMake is used to generate the MSVC Project files and drive the build.  A release
-and debug build is performed with a simple run of `ex1` to verify the executable.
-
-### Tests at LLNL
-
-- We mirror the `master` and `next` branches internally (to `gh-master` and
-  `gh-next`) and run longer nightly tests via cron. On the weekends, a more
-  extensive test is run which extracts and executes all the different sample

+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.

+    <one line to give the library's name and a brief idea of what it does.>

+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of

+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:

-##################################################################################

-#
-# This module implements standard behavior for XSDK CMake projects.  The main
-# thing it does in XSDK mode (i.e. USE_XSDK_DEFAULTS=TRUE) is to print out
-# when the env vars CC, CXX, FC and compiler flags CFLAGS, CXXFLAGS, and
-# FFLAGS/FCFLAGS are used to select the compilers and compiler flags (raw
-# CMake does this silently) and to set BUILD_SHARED_LIBS=TRUE and
-# CMAKE_BUILD_TYPE=DEBUG by default.  It does not implement *all* of the
-# standard XSDK configuration parameters.  The parent CMake project must do
-# that.
-#
-# Note that when USE_XSDK_DEFAULTS=TRUE, then the Fortran flags will be read
-# from either of the env vars FFLAGS or FCFLAGS.  If both are set, but are the
-# same, then FFLAGS it used (which is the same as FCFLAGS).  However, if both
-# are set but are not equal, then a FATAL_ERROR is raised and CMake configure
-# processing is stopped.
-#
-# To be used in a parent project, this module must be included after
-#
-#   PROJECT(${PROJECT_NAME}  NONE)
-#
-# is called but before the compilers are defined and processed using:
-#
-#   ENABLE_LANGUAGE(<LANG>)
-#
-# For example, one would do:
-#
-#   PROJECT(${PROJECT_NAME}  NONE)
-#   ...
-#   SET(USE_XSDK_DEFAULTS_DEFAULT TRUE) # Set to false if desired
-#   INCLUDE("${CMAKE_CURRENT_SOURCE_DIR}/stdk/XSDKDefaults.cmake")
-#   ...
-#   ENABLE_LANGUAGE(C)
-#   ENABLE_LANGUAGE(C++)
-#   ENABLE_LANGUAGE(Fortran)
-#
-# The variable `USE_XSDK_DEFAULTS_DEFAULT` is used as the default for the
-# cache var `USE_XSDK_DEFAULTS`.  That way, a project can decide if it wants
-# XSDK defaults turned on or off by default and users can independently decide
-# if they want the CMake project to use standard XSDK behavior or raw CMake
-# behavior.
-#
-# By default, the XSDKDefaults.cmake module assumes that the project will need
-# C, C++, and Fortran.  If any language is not needed then, set
-# XSDK_ENABLE_C=OFF, XSDK_ENABLE_CXX=OFF, or XSDK_ENABLE_Fortran=OFF *before*
-# including this module.  Note, these variables are *not* cache vars because a
-# project either does or does not have C, C++ or Fortran source files, the
-# user has nothing to do with this so there is no need for cache vars.  The
-# parent CMake project just needs to tell XSDKDefault.cmake what languages is
-# needs or does not need.
-#
-# For example, if the parent CMake project only needs C, then it would do:

-                  To test with a parallel build, the parallel (-p|-par) option

-      <var>=<value>
-                  Set a shell script variable; see below for valid variables
-       *          Any other parameter is treated as <mfem_dir>
-      <mfem_dir>  [${mfem_dir}] is the MFEM source directory

-   This script tests all the sample runs listed in the beginning comments of
-   MFEM's serial or parallel example and miniapp codes. The list of sample runs
-   is auto-generated and can be viewed with the -s|-show option.
-
-   The following shell script variables can be set with <var>=<value>:
-      output_dir [${output_dir}]
-         Same as '-o': if not empty, save output to files in that directory
-      output_sfx [${output_sfx}]
-         Suffix to append to the output files
-      mfem_config [${mfem_config}]
-         Set MFEM configuration options
-      make [${make}], mpiexec [${mpiexec}], mpiexec_np [${mpiexec_np}]
-         Their values can also set using the respective uppercase environment
-         variable
-      mfem_build_dir [${mfem_build_dir}]
-         Same as '-d': set this variable to something different from <mfem_dir>
-         to use an out-of-source build
-
-   For other valid variables, see the script source.
