1131# @USAGE: [options] [directory|file]
1132# @DESCRIPTION:
1133# If no arguments supplied, it will recompile not recursively all modules
1134# under sys.path (eg. /usr/lib/python2.6, /usr/lib/python2.6/site-packages).
1135#
1136# If supplied with arguments, it will recompile all modules recursively
1137# in the supplied directory.
1138# This function should only be run in pkg_postinst(). 2739# This function can be used only in pkg_postinst() phase.
1139#
1140# Options passed to this function are passed to compileall.py.
1141#
1142# Example:
1143# python_mod_optimize ctypesgencore
1144python_mod_optimize() { 2740python_mod_optimize() {
1145 # Check if phase is pkg_postinst(). 2741 if [[ "${EBUILD_PHASE}" != "postinst" ]]; then
