- export library path for gmp/mpfr from CGAL config files. This is required when non-system gmp/mpfr libraries are being used, but not using a ThirdParty compiler installation. - automatically handle lib/ vs lib64/ (eg, for central installations) for packages such as boost, CGAL, etc. While the ThirdParty compilation of these will normally land in lib64/, this may not be the case when they are supplied by another means. - reworked the handling of foamEtcFile and foamCleanPath for less clutter in the configuration files. Added the bin/tools/lib-dir script to handle logic that is too complex to easily manage in csh.
Misc. tools, scripts, templates that are useful (eg, for building applications) but don't need to be in the PATH.
