         The <span style="font-family:monospace"><span class="command"><strong>FormBroker</strong></span></span> package creates instances of 
         form data description objects. These objects instances have
         a simple set of methods to validate and control data
         as typically posted by HTML forms,
         thus data represented as the map of form variables
         to their values. In Rivet this association can be obtained either
         calling <a class="xref" href="load_response.html" title="load_response">load_response</a> or
         <a class="xref" href="var.html" title="var">var, </a> (form variables can be selectively
         read also calling <span style="font-family:monospace"><span class="command"><strong>::rivet::var_post</strong></span></span> or
         <span style="font-family:monospace"><span class="command"><strong>::rivet::var_qs</strong></span></span>)

      	The <span style="font-family:monospace"><span class="command"><strong>FormBroker</strong></span></span> package is still experimental. 
      	Basic functionalities and interface are not likely to change but
      	internal details and implementation could be redesigned
      	in future releases. More specifically the external validator mechanism
			will likely need design improvements.
