In July 2014 the layout of /usr/share/doc was drastically rearranged.
Because of the lack of rename support in CVS, the source dirs for the
docs have not yet been rearranged to match. (And also, many of the
source dirs are scattered across the tree and are hard to find
anyhow.)
The following is a hopefully complete list of the /usr/share/doc docs
and where they come from. For things in external, I've listed where
the makefiles that install the docs are; these point to the doc
sources, which are usually somewhere somewhat different.
