        This is the point of pristine-tar. For every upstream release,
 there is one commit  each into the upstream and pristine-tar brnaches;
 together, these commits allow one to recreate, bit for bit, the
 upstream tarball, so the  user may check any crypto checksums upstream
 provides.

        My build process looks for a orig,tar.gz file, and if that is
 missing, can create it from pristine-tar and upstream branches.

        Now, these branches contain every bit that came from
 upstream. My  integration branch, however, does not contain any file
 autogenerated by gcc, flex, bison -- or  autotools. The clean target,
 in fact, removes all the autogenerated files. Usually, topic--debian
 contains a commit that removes these files.
