Sounds good. I looked briefly at this when I packaged doxygen, but found the many dependencies meant that this is quite an

That would work, but I would suggest strongly considering packaging the additional libraries as individual packages, and linking 
them dynamically. I took this approach with Subversion's dependencies (apr, apr-util, neon), and it has paid off rather well in 
terms of decreased build times of the main package, and the ability to fix bugs in dependencies independently of the dependant

Wow, that is a *long* ldesc. I'd suggest just the first 2 paragraphs should be ldesc, and put the entire thing in the 
Cygwin-specific README file.

That external-source line is wrong, check the website docs again.
