This command is deprecated. It is used to maintain an \s-1SRP\s0 (secure remote
password) file. At most one of the \fB\-add\fR, \fB\-modify\fR, \fB\-delete\fR, and \fB\-list\fR
options can be specified.
These options take zero or more usernames as parameters and perform the
appropriate operation on the \s-1SRP\s0 file.
For \fB\-list\fR, if no \fIuser\fR is given then all users are displayed.
.PP
The configuration file to use, and the section within the file, can be
specified with the \fB\-config\fR and \fB\-name\fR flags, respectively.
