# Script
#     . change-sitedir.sh PREFIX [SUFFIX]
#
#     Shortcuts (prefix)
#         -prefix         "$WM_PROJECT_INST_DIR/site"
#         -project        "$WM_PROJECT_DIR/site"

#
#     Shortcuts (suffix)

#
# Description
#     Change WM_PROJECT_SITE, FOAM_SITE_APPBIN, FOAM_SITE_LIBBIN
#     and the respective entries in PATH, LD_LIBRARY_PATH.
#
#     This can be useful when temporarily reassigning the site directory
#     when packaging OpenFOAM.
#
#     The suffix value should normally include "platforms/$WM_OPTIONS"
#
# Example
#     . /path/change-sitedir.sh -prefix -platforms
#
#   corresponds to the standard site location:
#
#     $WM_PROJECT_INST_DIR/site{/$WM_PROJECT_VERSION/platforms/$WM_OPTIONS}
