Have you found yourself wanting to use Drupal for a site, but before management will sign off on it, you have to incorporate a few modules or applications from the "legacy" site? And management *won't* sign off on a complete rewrite? And the module or application in question is so unique that there exists no pre-existing Drupal module? Where do you start? What do you even do in such a situation? In this class, I discuss that scenario (which I myself was facing) and the techniques I used to get a foreign module to run from Drupal, with as little change to the foreign module as possible (due to budget and time contraints).
