I've just added a new project, which is something that's been around for a long time but has only now been released under GPL.
It's written in 'Progress 4GL', a proprietary language used to interact
... [More] with the Progress RDBMS.
Ohloh doesn't have this language listed - not surprising really, I gues :-)
The project in question is:
https://www.ohloh.net/projects/apms
The files that are in Progress are the .p, .i and .w files.
