Redmine

Hi

I would like to be able to get more information on which OSS the projects hosted on my Redmine platform are using.
Is there any plugin indexing the repositories that could then be search against public database like Google codesearch, koders.com or others ?
Applications of this could be:
- make sure your software do not embed any unauthorized third parties,
- embed appropriate licenses and credits when delivering your software,
- retrieve automatically a source file by method name.

Regards
