 Get it from Debian, of course.  `apt-get source rscheme' will pull it
 in if you run Debian GNU/Linux.  Otherwise, look for it in:

 <URL:http://http.us.debian.org/debian/dists/woody/main/source/devel/>

 You should probably grab both the .tar.gz and the .diff.gz files, and
 apply the Debian .diff.gz after looking it over for any patches
 they've made to the upstream sources outside of the usual "debian/*"
 subdirectory.  (Sometimes there's a "configure" patch that sneaks in
 because `autoconf' was run.  It can usually be ignored when you
 review the patch for relevant details.)

 I'm looking forward to learning how it works.  I don't understand
 compilation very well yet.
