<!--
 We show all the subcommands using XML that looks like this:

  <term>
    <cmdsynopsis>
      <command>list_connections</command>
      <arg choice="opt">
      <replaceable>connectioninfoitem</replaceable>
       ...
      </arg>
    </cmdsynopsis>
  </term>

 However, while DocBook renders this sensibly for HTML, for some reason it
 doen't show anything inside <cmdsynopsis> at all for man pages. I think what
 we're doing is semantically correct so this is a bug in DocBook. The following
 rules essentially do what DocBook does when <cmdsynopsis> is not inside a
 <term>.
