# File

#
# Description
#     The OpenFOAM environment for POSIX shell (eg, bash,dash,zsh,...).
#     Source manually or from the ~/.bashrc or ~/.profile files.
#
#     Many settings can be overridden using a <prefs.sh> file:
#
#       - Base values (eg, from system admin):
#         -  $WM_PROJECT_DIR/etc/prefs.sh
#
#       - User or group values (first file found):
#         -  ~/.OpenFOAM/$WM_PROJECT_VERSION/prefs.sh
#         -  ~/.OpenFOAM/prefs.sh
#         -  $WM_PROJECT_SITE/site/$WM_PROJECT_VERSION/prefs.sh
#         -  $WM_PROJECT_SITE/site/prefs.sh
#
# Environment
#     FOAM_VERBOSE (set/unset)
#         - add extra verbosity when sourcing files
#     FOAM_CONFIG_NOUSER (set/unset)
#         - suppress use of user/group configuration files
#
# Note
#     Changes made to this bashrc file may be lost with the next upgrade.
