I found some time today to implement a script to generate the tarball 
files for dtv-scan-tables at the LinuxTV server.

The script runs daily, checking if there was any new changeset at the
repository. If it finds a new changeset there, it will take the date
and the changeset of the latest commit at the tree and them as part of
the tarball name, adding them to the following directory:

	http://linuxtv.org/downloads/dtv-scan-tables/

The script will also create an hyperlink of the latest tarball at:
	dtv-scan-tables-LATEST.tar.bz2

Every time a new file is added there, it will also update the md5sum file,
that could be used by someone to check the downloads.
