+  <para>The <filename>shells</filename> file contains a list of
+  login shells on the system. Applications use this file to determine
+  whether a shell is valid. For each shell a single line should be
+  present, consisting of the shell's path, relative to the root of the
+  directory structure (/).</para>
+
+  <para>For example, this file is consulted by <command>chsh</command>
+  to determine whether an unprivileged user may change the login shell for her
+  own account. If the command name is not listed, the user will be denied of
+  change.</para>

+  with shells not included in this file.</para>
