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> 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.
