Here's one way that preserves a distinct identity for the library sources.
It should work with Windows or Unix.  It just checks to see if the library
is installed, using the protocol header file as an indicator, and if it
isn't there, it grabs it off the internet, untars it, and installs it.

The patch is to DynamicGraph, an example of an app that depends on a library,
namely graph-2.1.tar.gz.

That's what I mean by makefile logic.  If you want to aggregate library
sources in one tarball, then perhaps what you want is a "dist" target
that creates a distribution directory, populates it, and tars it up.

Your working area could then still have a symlink to some CVS reference
area.

If you symlink the whole directory and cd into that then you are in
that directory, and a commit there will do the right thing.

If you symlink the files, then you will have to go into the reference
directory and run cvs commit there.
