I've worked with SilverStripe on several non-production sites just trying to learn the system. I've created a few modules from scratch and incorporated those within the site with no problem. One thing I have run into several times is needing a way to detect if a particular module is installed.
Is there a "SilverStripe way" of doing this? Something along the lines of Controller::moduleExists('module_name')? It seems like this should be a fairly common need from SS developers so I'm hoping someone has a simple method to do module detection.
