+    <title>DESCRIPTION</title>
+    <para>
+      The <function>pam_putenv</function> function is used to
+      add or change the value of PAM environment variables as
+      associated with the <emphasis>pamh</emphasis> handle.
+    </para>
+    <para>
+      The <emphasis>pamh</emphasis> argument is an authentication
+      handle obtained by a prior call to pam_start().
+      The <emphasis>name_value</emphasis> argument is a single NUL
+      terminated string of one of the following forms:
+    </para>
+    <variablelist>
+      <varlistentry>
+        <term>NAME=value of variable</term>
+        <listitem>
+           <para>
+             In this case the environment variable of the given NAME
+             is set to the indicated value:
+             <emphasis>value of variable</emphasis>. If this variable
+             is already known, it is overwritten. Otherwise it is added
+             to the PAM environment.
+          </para>

+          <para>
+            This function sets the variable to an empty value. It is
+            listed separately to indicate that this is the correct way
+            to achieve such a setting.
