Alright, here's a patch for your perusal. It differs from yours in that:
* Variables have been renamed.
* Your auxiliary buffers may need to hold as many as 10 digits
for uid_t and gid_t, which are currently unsigned 32-bit ints.
* You _must_ keep usage() in sync with your getopt() rules.
* I've added a diff for the manpage.
Ciao,
Sheldon.
