580# @USAGE: [options] [directory|file]
581# @DESCRIPTION:
582# If no arguments supplied, it will recompile not recursively all modules
583# under sys.path (eg. /usr/lib/python2.6, /usr/lib/python2.6/site-packages).
584#
585# If supplied with arguments, it will recompile all modules recursively
586# in the supplied directory.
587# This function should only be run in pkg_postinst(). 2687# This function can be used only in pkg_postinst() phase.
588#
589# Options passed to this function are passed to compileall.py.
590#
591# Example:
592# python_mod_optimize ctypesgencore
593python_mod_optimize() { 2688python_mod_optimize() {
