As some of you may know - I'm member of the JED team (http://extensions.joomla.org) since February this year. It is an interesting experience and a job that is extremely demanding... One needs to constantly approve/reject extensions and no matter how hard one works - there are always new extensions in the queue. Believe it or not one of the most common reasons to reject a listing is because it is missing an index.html file in a folder or "defined('_JEXEC') or die()" statement in the php files or a license tag.
Developers have been always talking and talking that those checks can be automated and when you submit an extension the JED should let you know if you don't pass a certain test/rule. On jandbeyond this year we were again talking about that and somebody suggested that we should create a component for this. And it struck me! All this time I thought that I needed access to the JED server to make changes to the software we run, but if I don't have this access - why not create an extension and make developers aware of it! If developers test their zip packages before they submit them to the JED, this could ensure that their submissions won't be rejected due to missing index.html files... This could save JED editors time and it could save developers time! And as we know time is money...
