unstable -> testing delay

[Groucho Marx <groucho@lanet.com.ar>]

Hi there.
There has been quite a dispute on this subject in one of the lists of
my local LUG. Perhaps someone here knows the answer:

>From footnote 19 on section 5.3 of the Debian Policy Manual, about the
"urgency" field of debian/changelog:

http://www.debian.org/doc/debian-policy/footnotes.html#19

Recognised urgency values are low, medium, high and emergency. They have an
effect on how quickly a package will be considered for inclusion into the
testing distribution, and give an indication of the importance of any fixes
included in this upload.

Exactly how long a package must wait in unestable before being included
into testing for every value of urgency? Is it automated of human-driven?


Thank you!
