=head1 NAME
ezmlm-web - A web configuration interface to ezmlm mailing lists
=head1 SYNOPSIS
ezmlm-web [B<-c>] [B<-C> E<lt>F<config file>E<gt>] [B<-d> E<lt>F<list directory>E<gt>]
=head1 DESCRIPTION
=over 4
=item B<-c> Disable list configuration
=item B<-C> Specify an alternate configuration file given as F<config file>
If not specified, ezmlm-web checks first in the users home directory, then in
F</etc/ezmlm> and then the current directory
=item B<-d> Specify an alternate directory where lists live. This is now
depreciated in favour of using a custom ezmlmwebrc, but is left for backward
compatibility.
