# $FreeBSD$
#
# Replace #! interpreters in scripts by what we actually have.
#
# Standard templates for bash, perl, python,... are included out of
# the box, others can easily be added per port.
#
# Feature: shebangfix
# Usage: USES=shebangfix
#
# To specify that ${WRKSRC}/path1/file and all .pl files in ${WRKSRC}/path2
# should be processed:
#
# SHEBANG_FILES= path1/file path2/*.pl
#
# To define a new shebang scheme add the following to the port Makefile:
#
# SHEBANG_LANG= lua
# lua_OLD_CMD= /usr/bin/lua
# lua_CMD= ${LOCALBASE}/bin/lua
#
# To override a definition, for example replacing /usr/bin/perl by
# /usr/bin/env perl, add the following:
#
# perl_CMD= ${SETENV} perl
#
# MAINTAINER: portmgr@FreeBSD.org
