From a77e638c773d8a492f8c48e8c15474030a7e3d71 Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Mon, 12 Dec 2011 22:36:57 +0100 Subject: contrib/*: Support the "--help" and "--version" options Add "--help"/"-h" and "--version"/"-V" support to all contrib scripts. Also, update scripts that used "-v" as a short option for "--version" and use "-V" for the sake of consistency. Additionally: * Move version and usage messages to separate convenience functions in all scripts. * Add a workaround to paccache to support "--help" and "--version". This should be replaced by a proper POSIX-compliant command line parser that supports long options in a future patch. * Add a "$myver" variable to all scripts and use it whenever we refer to the program version (e.g. in version messages). Also, use the pacman version number everywhere instead of using a different versioning scheme for each contrib script. This is achieved by adding a "PACKAGE_VERSION" placeholder that is replaced by sed(1) when the script is built. * Ensure we always return with exit status 0 if "--help" is used and return with exit status 1 if we display the usage message due to invalid arguments. * Add "AUTOMAKE_OPTIONS = std-options" and add all scripts to "bin_SCRIPTS" to make `make installcheck` check that installed scripts actually support the "--help" and "--version" options.
