1141# @USAGE: [options] [directory|file]
1142# @DESCRIPTION:
1143# If no arguments supplied, it will recompile not recursively all modules
1144# under sys.path (eg. /usr/lib/python2.6, /usr/lib/python2.6/site-packages).
1145#
1146# If supplied with arguments, it will recompile all modules recursively
1147# in the supplied directory.
1148# This function should only be run in pkg_postinst(). 2787# This function can be used only in pkg_postinst() phase.
1149#
1150# Options passed to this function are passed to compileall.py.
1151#
1152# Example:
1153# python_mod_optimize ctypesgencore
1154python_mod_optimize() { 2788python_mod_optimize() {
1155 # Check if phase is pkg_postinst(). 2789 if [[ "${EBUILD_PHASE}" != "postinst" ]]; then
