Conditional File Include

[Dashamir Hoxha]

Sometimes, small WebBox-es with a single line, like this:
    <WebBox ID="box_id">
      <Include SRC="{{./}}{{file}}" />
    </WebBox>
are used to include a file according to some condition.

Maybe it is better to use another more specific syntax, like this:
    <FileSwitch ID="switch_id" FILE="{{...}}" />

In this case, the file 'switch_id.php' will contain the PHP code
that will actually decide which file is going to be included
(according to the state of the application). It will be something
like this:
    <?php
    class switch_id extends FileSwitch
      {
        function init()   { . . . }
        function switch() { . . . }
      }
    ?>
where FileSwitch extends WebObject (so it may have state variables)
and the function switch() is called during the parse (similar to
function onParse() of the WebObject).
