Get your bash scripts to handle options (-h, --help etc) and spit out auto-formatted help or man page when asked!!
This will make your bash scripts better!! process-getopt is a wrapper around getopt(1) for bash that lets you define command line options (eg -h, --help) and descriptions through a single function call. These definitions are then used in runtime processing of command line options as well as in generating help and man pages. It also saves a little time in coding and in producing nicely formatted documentation. It is quite similar to GNU's argp in glibc for compiled languages and OptionParse for python. See: Linux Gazette article 162: http://tldp.org/LDP/LGNET/162/hepple.html, http://sourceforge.net/projects/process-getopt, http://bhepple.freeshell.org/oddmuse/wiki.cgi/process-getopt
