title: which open source projects used Mylyn plugin?
body: <p>I know that by using Mylyn plug-in we can track developer's interaction with different parts of source code. In Eclipse Bug tracking system (Bugzilla) for most of the issues there is an attachment file called mylyn-context.zip which includes all the interaction history collected from Mylyn for this specific bug. I'm wondering is there any other open source projects which use Mylyn and their developers attached the same file (mylyn-context.zip) to the project's issue tracking system?</p>
