From 264021699cb9a460ebcdd3d080e88d55c269cc61 Mon Sep 17 00:00:00 2001 From: Karel Zak Date: Tue, 5 Jun 2007 23:29:32 +0200 Subject: New program: arch * NEWS: Mention arch. * README: Add arch to the list of programs. * AUTHORS: Add arch. * src/uname.c: Include "uname.h". (PROGRAM_NAME): Handle arch, too. (ARCH_AUTHORS): Define. (uname_long_options, arch_long_options): Renamed and new globals. (usage): Handle arch-mode as well as uname-mode. (decode_switches): New function, extracted from main, to handle arch-mode as well as uname-mode. (main): Handle both modes. * src/uname-arch.c: New program, alias for "uname -m". * src/uname-uname.c: New file, default uname mode. * src/uname.h: New file, uname modes. * src/Makefile.am (EXTRA_PROGRAMS): Add arch. (uname_SOURCES, arch_SOURCES): Define. * man/arch.x: New file. * man/Makefile.am (dist_man_MANS): Add arch.1. (arch.1): New dependency. * tests/misc/arch: New test, compare "arch" with "uname -m" * configure.ac (OPTIONAL_BIN_PROGS): Add arch. (MAN): Add arch.1. * .x-sc_require_config_h: Exempt uname-arch.c and uname-uname.c from the always-include- rule.
