Ljcom
From Dreamwidth Notes
Only look at ljcom if you have a specific reason--we want people who are able to sign affadavits that they have not seem the ljcom code and are thus able to do clean room implementations.
If you want to look at ljcom code, you can check it out like this:
svn co http://code.livejournal.org/svn/ljcom/trunk/ ljcom
BUT ONLY USE IT AS AN EXAMPLE. We can't use code from that repository; it belongs to LiveJournal and is not open source.
