Deletion of Trac (2nd nomination)

Comment: Covered in a couple more books (which don't have trac in title) http://books.google.com/books?id=5ISfkblE9AUC&pg=PA756 http://books.google.com/books?id=LeJnpIQ40VEC&pg=PT533 also at length, so I think it passes . Also compared with Bugzilla in another book http://books.google.com/books?id=UVlgr2TTwCAC&pg=PT391 here. There are some ~450 GS hits that mention it together with bugzilla http://scholar.google.com/scholar?as_q=trac+bugzilla&as_epq=&as_oq=&as_eq=&as_occt=any&as_sauthors=&as_publication=&as_ylo=&as_yhi=&btnG=&hl=en&as_sdt=0%2C5
Stance: keep
