In trunk we have added About section in Settings. Because we have already some plugins on AGPL license we need a place in the UI to provide links to their source code.
All plugin authors are encouraged to create/update packag.xml files.
There's still one issue. How to define URL of plagin source. There's <srcuri> tag which I think we should use. However, I have problems with validation according to defined XSD for this file. Any hints? Till?
