From: mhb Date: Sat, 25 Apr 2009 03:35:45 +0000 (+0000) Subject: Added GNUish options --help, --quiet, --silent and --version. X-Git-Tag: 20090517-FFI~31 X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=a7a940cc0c31ec4e0c0d4c22a15a70610f0a41b1;p=mit-scheme.git Added GNUish options --help, --quiet, --silent and --version. Converted old comment about machine options into new function print_help(). Hack argv at the end of parse_options() to get --help and --version through to the band.
