#     Set OpenFOAM environment for C-shell (csh, tcsh).
#     Source manually or from the ~/.login or ~/.cshrc files.
#
# Note
#     Many environment variables can be overridden using a <prefs.csh> file
#     from one of these locations:
#     * user-specific:
#         * ~/.OpenFOAM/$WM_PROJECT_VERSION
#         * ~/.OpenFOAM
#     * group-specific:
#         * $WM_PROJECT_SITE/site/$WM_PROJECT_VERSION
#         * $WM_PROJECT_SITE/site
#     * general:
#         * $WM_PROJECT_DIR/etc
