  <h3>About Clients</h3>

  <p>The client system provides a way to organise your commissions into
     categories, based on who the job is for or any other criteria that may be
     convenient.&nbsp; The &ldquo;clients&rdquo; in <?php echo APPNAME; ?> do
     not actually have to correspond to real people or organisations.&nbsp; For
     example, if you sometimes sell shoes and sometimes sell shirts, you could
     create a &ldquo;client&rdquo; for each.&nbsp; You can also create clients
     that belong to other clients, so, following on from the previous example,
     within shoes, you could create clients representing all the people you sell
     shoes to, and within shirts, you could create clients for all the people
     who buy shirts.</p>
