It'd be nice if maketarball built the docs and put them in the
right place to automate generating release tarballs.

Something like this:


1. add support for a -r flag indicating this is a release tarball
2. write the -r code which builds the html and texinfo docs and
   puts them in the right place in the tarball

Assigning to me and putting in the 0.0.4 target.

Pretty sure we need to go through and update the copyright
statements for 2012.

Also, while doing this pass, we should double-check that the FSF
doesn't own the copyrights--they disclaimed them. Probably should
assign copyrights on a file-by-file basis to whoever
authored/edited them based on what git says.

Putting this in the 0.2.1 target.

I'll take it if no one else does by the weekend.
