+    <title>DESCRIPTION</title>
+
+    <para>
+      <emphasis>unix_chkpwd</emphasis> is a helper program for the
+      <emphasis>pam_unix</emphasis> module that verifies the
+      password of the current user. It also checks password and account
+      expiration dates in <emphasis>shadow</emphasis>. It is not intended to
+      be run directly from the command line and logs a security violation if
+      done so.
+    </para>
+
+    <para>
+      It is typically installed setuid root or setgid shadow.
+    </para>
+
+    <para>
+      The interface of the helper - command line options, and input/output
+      data format are internal to the <emphasis>pam_unix</emphasis>
+      module and it should not be called directly from applications.
