Copyright for at source package in Xenial

Format: http://www.debian.org/doc/packaging-manuals/copyright-format/1.0/
Upstream-Name: at
Source: git://anonscm.debian.org/collab-maint/at.git
Comment: 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.
