Check getflags(8)[1], it parse options and generate usage messages for
rc scripts.

For C there are ARGBEGIN, ARGEND[2] and other macros. They don't
generate usage, but they solve another problem of getopt(): you don't
have to check that the string that you pass to getopt() lists all
options that you accept in switch.
