#!/bin/sh
#
# Trigger to compile python code into native bytecode and remove
# generated bytecode files.
#
# Packages need to set the variable pycompile_dirs with a list
# of directories (absolute path) separated by spaces, and WITHOUT
# the first slash, e.g:
#
# pycompile_dirs="usr/blah/foo usr/zoo/d00d"
#
# or if the code resides in standard site-packages directory,
# need to set the pycompile_module variable:
#
# pycompile_module="blah foo"
#
# Or if a module is stored in top-level site-packages directory:
#
# pycompile_module="foo.py"
#
# Arguments:	$ACTION = [run/targets]
#		$TARGET = [post-install/pre-remove]
#		$PKGNAME
#		$VERSION
#		$UPDATE = [yes/no]
#
