Most applications written in C use system getopt(3) or getopt_long(3)
and therefore follow these guidelines. These guidelines show how
applications usually work, not only standardized `cat', `cut', `grep'
etc. and I think apps written in Lua shell follow these rules too
_by default_ just like all C application. Unfortunately I don't see
such module for Lua.
