Well, the examples I have are technically better than no examples at all --
take a look at /usr/lib/getopt/parse.bash & see what I mean.

If you are just thinking of one flag or option to the script, take a look
at the K & S scripts in /etc/rc.d/init.d: they all use the "case" branching
command to do what you're thinking about. And it will be much easier to
implement than getopt.
