# SYNOPSIS:
#
# Automake magic to handle the various tasks of building scripts. Scripts can
# be built down to extensionless executables (e.g., foo.pl -> foo), or to
# files with the usual extension (foo-lib.sh.in -> foo.sh).
#
# Files which support it are syntax-checked when the user invokes 'make check',
# unless the Makefile.am defines SKIP_CHECKS.
#
# All *target* filenames must be listed in SCRIPTS_SHELL, SCRIPTS_PERL, and
# SCRIPTS_AWK to support 'make dist', and 'make distclean'. No files which are
# not substituted by config.status should be included in SCRIPTS_PERL,
# SCRIPTS_SHELL, or SCRIPTS_AWK. If non-generated files are listed for
# installation, then Automake will figure out that they should be distributed;
# otherwise, include them in EXTRA_DIST.
#
# All SCRIPTS_SHELL and SCRIPTS_PERL are syntax-checked on 'make check'. There is
# a fix in place to run these syntax checks against the perl modules in the build
# tree, rather than against the (potentially old) installed perl modules.
#
# To emulate EXTRA_DIST for scripts, use SCRIPTS_EXTRA_DIST, e.g.,
# SCRIPTS_SHELL = $(selected_scripts)
# SCRIPTS_EXTRA_DIST = $(all_scripts)
#
# USAGE:
#
# include $(top_srcdir)/config/automake/vars.am
# include $(top_srcdir)/config/automake/scripts.am
# ...
# SCRIPTS_PERL = fooscript barscript perl-lib.pl perlmod.pm
# SCRIPTS_PERL_NO_CHECK = no_check_script
# SCRIPTS_SHELL = shell1 shell2 sh-lib.sh
# SCRIPTS_AWK = talk balk chalk awk-lib.awk
# sbin_SCRIPTS = not-subbed
# SCRIPTS_EXTRA_DIST = util-script
#
# with the corresponding files in the repository:
#
# fooscript.pl barscript.pl perl-lib.pl.in perlmod.pm.in
# no_check_script.pl
# shell1.sh shell2.sh sh-lib.sh.in
# talk.awk balk.awk chalk.awk awk-lib.awk.in
# not-subbed util-script.pl
#
# To add extra flags to the perl checks (e.g., to add new -I flags), set
# CHECK_PERL_FLAGS.
# Implementation note:
#
# This file uses config.status to substitute @foo@ in those scripts while
# converting them. It also adds the executable bits (a+x) to extensionless
# files. The substitution works even though the files are not listed in
# configure.in
# Perl
