README.source Packaging TeX Live for Debian is a huge task. Development is done in a very specific layout and source packages are generated from that. If you want to know how the *orig.tar.gz* and the *source* packages are generated, please check out the Debian TeX Live packaging infrastructure at http://anonscm.debian.org/gitweb/?p=debian-tex/texlive-nonbin.git where you will find a README file explaining everything in detail. Or get it at http://anonscm.debian.org/gitweb/?p=debian-tex/texlive-nonbin.git;a=blob_plain;f=README
