-  <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

-  <para>It is a requirement for applications such as
-  <application>GDM</application> which does not populate the
