    Access Control Lists are fine grained permissions. Perhaps you
want to allow Sam to read a file and for Ted to both read and write
it. These permissions should not need to be reset every time you
modify the file.

   Since I am a member of both "staff" and "everyone", I can set group
on one of my files from "staff" to "everyone" or back again:

$ chown :everyone x.pl
$ ls -la x.pl
-rwxrwxrwx  1 nyamatongwe  everyone  269 Mar 11  2008 x.pl
$ chown :staff x.pl
$ ls -la x.pl
-rwxrwxrwx  1 nyamatongwe  staff  269 Mar 11  2008 x.pl
