first version of a FusionForge lister (T778)
This is the first attempt at writing a lister for projects hosted on a FusionForge instance, like for instance:
- gforge.inria.fr (T390)
- adullact.net (T775)
- sourcesup.renater.fr
Currently, the lister only considers git and svn repositories and works quite well with
the three forge cited above. It should also work with other FusionForge instances if
the url schemes for their hosted repositories can be handled by the current implementation.
