"# $Id$" lines will be removed from the tree. The devmanual should reflect that change. Also, two sections about CVS keyword expansion were previously changed to Git, which however doesn't expand those keywords. I'll attach a series of 3 patches for review.
Created attachment 465294 [details, diff] ebuild-writing: The ebuild header doesn't have an $Id$ line any more.
