# Description
|
|
# Locate user/group/shipped file with semantics similar to the
|
|
# ~OpenFOAM/fileName expansion.
|
|
#
|
|
# The -mode option can be used to allow chaining from
|
|
# personal settings to site-wide settings.
|
|
#
|
|
# For example, within the user ~/.OpenFOAM/<VER>/prefs.sh:
|
|
# @verbatim
|
|
# foamPrefs=`$WM_PROJECT_DIR/bin/foamEtcFile -m go prefs.sh` \
|
|
# && _foamSource $foamPrefs
|
|
# @endverbatim
