     28 =head1 DESCRIPTION
     29 
     30 This command is deprecated. It is used to maintain an SRP (secure remote
     31 password) file. At most one of the B<-add>, B<-modify>, B<-delete>, and B<-list>
     32 options can be specified.
     33 These options take zero or more usernames as parameters and perform the
     34 appropriate operation on the SRP file.
     35 For B<-list>, if no I<user> is given then all users are displayed.
     36 
     37 The configuration file to use, and the section within the file, can be
     38 specified with the B<-config> and B<-name> flags, respectively.
