This is undocumented and unofficial, so feel free to utterly ignore it
and commit whatever the heck you want.

The 'doc' and 'examples' (yay for consistency!) USE flags are intended
for use where building documentation or examples would take a long
time, introduce new dependencies or otherwise be an inconvenience to
many users.

For example, if libiamafish comes with a half dozen small example
source files and a few pages of HTML, just install them. If, however,
libiamafish requires, say, doxygen to generate its documentation, or
comes with several megabytes of examples in a separate tarball, then
you should consider a USE flag.

Explanation: a USE flag for trivial stuff that isn't in /etc, doesn't
slow anything down, doesn't introduce any dep bloat and generally
doesn't change anything noticeable isn't a USE flag that's giving the
user any meaningful choice or making things easier for arch teams. You
do not get bonus points for using more USE flags.
