Well, sort of.  Under 4.2bsd and its descendants (4.3, Ultrix, Sun,
etc), you can be in multiple groups at once; files are owned by a
single group, which is by default the same as that of the directory
the file is created in, though the owner can change the group of a file
to any group the owner is a member of.  Under all other Unixes,
you can be authorized to be in multiple groups (in the /etc/group
file) but at any given time you are in only one group.  However, you
can use "newgrp" to "log in" to a different group.
