Copyright for at source package in Squeeze

This is the Debian GNU/Linux prepackaged version of the deferred
execution scheduler called at.

This package was debianized by its author Thomas Koenig
, taken over and re-packaged first by Martin
Schulze  and then by Siggy Brentrup ,
and then taken over by Ryan Murray .

In August 2009 the upstream development and Debian packaging were taken over
by Ansgar Burchardt  and Cyril Brulebois .

This may be considered the experimental upstream source, and since there
doesn't seem to be any other upstream source, the only upstream source.
