# 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
#
# SHEBANG_REGEX a regular expression to match files that needs to be converted
# SHEBANG_FILES list of files or glob pattern relative to ${WRKSRC}
# SHEBANG_GLOB list of glob pattern find(1) will match with
#
# To specify that ${WRKSRC}/path1/file and all .pl files in ${WRKSRC}/path2
# should be processed:
#
# SHEBANG_FILES= path1/file path2/*.pl
#
# To define custom shebangs to replace, use the following (note that
# shebangs with spaces should be quoted):
#
# perl_OLD_CMD= /usr/bin/perl5.005 "/usr/bin/setenv perl5.005"
#
# 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
