checkgid - checks the gid
This manual page documents briefly the checkgid
is a program that checks whether it can setgid to the group
specified. This is to see if it is a valid group for apache2 to use at
runtime. If the user (should be run as superuser) is in that group, or can
setgid to it, it will return 0.
This manual page was written by Daniel Stone <email@example.com> for the
Debian GNU/Linux distribution, as the original did not have a manpage.
