# $NetBSD: replace-interpreter.mk,v 1.13 2013/04/18 00:24:48 mspo Exp $
# This file provides common templates for replacing #! interpreters
# in script files.
#
# The following variables may be set by a package:
#
# REPLACE_AWK
# REPLACE_BASH
# REPLACE_CSH
# REPLACE_KSH
# REPLACE_PERL
# REPLACE_SH
# Lists of files relative to WRKSRC in which the #! interpreter
# should be replaced by the pkgsrc one. If any directories
# appear in the lists, they are silenty skipped, assuming that
# they result from shell globbing expressions.
#
# Use REPLACE_SH for shell programs that don't need any
# special features from bash, and REPLACE_BASH for the
# others.
#
# Note that in all the above cases, you have to add the needed
# tools manually to USE_TOOLS, since there is no way to detect
# automatically whether a tool should be a build-time or a
# run-time dependency.
#
# Packages may also add their own interpreter replacements, which should
# just look like the examples below. For the REPLACE_INTERPRETER
# variable, all identifiers starting with "sys-" are reserved for the
# pkgsrc infrastructure. All others may be used freely.
#
# Keywords: replace_interpreter interpreter interp
