libMesh-specific implementation features:
source and header files must be listed explicitly.
When adding a header file,
1.) svn add the file
2.) cd include ; ./rebuild_include_HEADERS.sh
3.) cd include/libmesh ; ./rebuild_makefile.sh
When adding a soure file,
1.) svn add the file
2.) cd src ; ./rebuild_libmesh_la_SOURCES.sh
General notes:
o make install && make installcheck
installs the built library & performs sanity checking
o make distcheck
packages up a tarball and tests it for self-sufficiency.
always do this when modifying the build system.
o for more information, view the README and INSTALL files.
* VariableGroups DofObject storage optimization for the common
case of multiple Variables of the same type within a System.
Note this changes the default variable ordering within a
System - the old format is available via System::identify_variable_groups()
* TecplotIO binary format updated to support v11.2 features where
available. This includes encoding the solution time into output files,
writing each libMesh subdomain to a separate Tecplot zone, and support
for 1D Tecplot binary files.
* ./configure'able support for identifier types. Defaults:
id size (boundaries)............. : 2 bytes
id size (dofs)................... : 4 bytes
id size (processors)............. : 2 bytes

* Reduced memory footprint for Node objects.
* Fix for using specified preconditioners with adaptivity and PETSc-3.3.
