Before releasing, make the following tests:

* build debs
  * debuild
* run lintian on *.changes, check you disagree with every warning/error
  * [debuild should do that]
* install all debs (there should be no conflicts)
  * dpkg -i *.deb
* deinstall all debs
  * dpkg --remove twisted-doc python2.1-twisted python2.2-twisted python-twisted
* install again
  * dpkg -i *.deb
* run python2.1 admin/runtests
* run python2.2 admin/runtests
* hack admin/accepttests to set bindir to /usr/bin and run 
  python2.1 admin/accepttests
* make sure distributed web servers are working; test on zaibach.
  * run a --user server on port 3080 
    ('mktap web --user -p 3080; twistd -f web.tap')
  * create a --presonal web server from own user
  * check it works
  * kill --user server
  * run tap2deb
  * install the deb
  * check it still works
  * dpkg --purge it
* repeat all last steps with python2.2: mktap->mktap2.2 etc.
* check t-im works
