It's generally impossible to figure out what files are binaries and
produced by the egg-setup and which are not (there might be executable
scripts that are part of the egg sources). So this is an attempt to
handle the usual case, even if it is not perfect.

During development it is essential. Some eggs contain a lot of code
and take long to compile. Once you have a setup file, it will become
difficult and error-prone to keep two different approaches to building
the egg (one for development and one for egg-setup).

Thanks. I will push it in a few moments.
