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.
