+.SH "NAME"
+pwhistory_helper \- Helper binary that transfers password hashes from passwd or shadow to opasswd
+.SH "SYNOPSIS"
+.HP \w'\fBpwhistory_helper\fR\ 'u
+\fBpwhistory_helper\fR [\&.\&.\&.]
+.SH "DESCRIPTION"
+.PP
+\fIpwhistory_helper\fR
+is a helper program for the
+\fIpam_pwhistory\fR
+module that transfers password hashes from passwd or shadow file to the opasswd file and checks a password supplied by user against the existing hashes in the opasswd file\&.
+.PP
+The purpose of the helper is to enable tighter confinement of login and password changing services\&. The helper is thus called only when SELinux is enabled on the system\&.
+.PP
+The interface of the helper \- command line options, and input/output data format are internal to the
+\fIpam_pwhistory\fR
+module and it should not be called directly from applications\&.

+.SH "AUTHOR"
+.PP
+Written by Tomas Mraz based on the code originally in
+\fIpam_pwhistory and pam_unix\fR
+modules\&.
