[Robby Workman]

CC'ing Pat, as we might need to consider the --enable-examples in a
future chmlib rebuild...

Okay, that's a bug.  If it's not fixed in the next day or so, then
that means I forgot about it, so ping me again.

Well, just damn.  What are the chances that we can do a package named
"chmlib-examples" which installs only the missing parts of chmlib
(similar to how we do exo-notify)?

Assuming the "chmlib-examples" package is possible, can you work one
of those up and mail the resulting tarballs (both chmlib-examples and
fixed chm2pdf) to me (unless the submit window has reopened by then,
in which case you can just submit them normally).
