Look in the Scons user Manual. Tar is bassically as it sounds, it puts files into a tar file. The 'Install' builder is bassically a copy operation. I could tar directly, but unfortenetely I needed to get the top level directory to be 'glob2-0.9.1', and there is no easy way to do this without copying all the files to a temporary first, and Install does this for me. > If I understand correctly, nothing gets executed until main() is called at > the > end of SConstruct?

All you need to do is set up a the env.Install, and use the Alias to make one 'debbuild' install all the files to the temporary deb directory.
