=head1 DESCRIPTION

This command is used to maintain an SRP (secure remote password) file.
At most one of the B<-add>, B<-modify>, B<-delete>, and B<-list> options
can be specified.
These options take zero or more usernames as parameters and perform the
appropriate operation on the SRP file.
For B<-list>, if no I<user> is given then all users are displayed.

The configuration file to use, and the section within the file, can be
specified with the B<-config> and B<-name> flags, respectively.
