=head1 get-logs.pl

Output webserver logs for a domain.

Given a domain name with the C<--domain> flag, this command outputs some or
all of it's Apache access or error log. The log file to display can be
selected with the C<--access-log>, C<--error-log> or C<--ftp-log> flag,
and the number of lines to output can be limited with the C<--tail> flag
followed by a line count.
