- foamCleanPath now only splits the environment variable on ':', which
allows other directories with spaces or '(..)' etc to pass through
without major issue.
- The filter arguments are split on whitespace, colons or semi-colons.
- 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.
- suppress error messages that appear with zsh.
According to unset(1p), 'unset -f' unsets a function.
If the function was not previously defined, this is a no-op.
This is similar for zsh, but there it emits a warning if the
function was not previously defined.
- avoid 'local' in functions sources from etc/bashrc.
ksh does not support this.
- use 'command' shell builtin instead of 'type'.
Seems to be more consistent between shell flavours.
- as per bashrc,cshrc delimit with
"# USER EDITABLE PART"
"# END OF (NORMAL) USER EDITABLE PART"
this can help simplify any patching for system-building scripts etc.
