Some thoughts about py{support,central} -> dh_python2 conversion

[Jakub Wilk <jwilk@debian.org>]

Dear all,

If you can't resist the urge to convert your packages from 
python-support to dh_python2, then please at least:

1) Test your packages. Don't assume that the helper you use does the 
right thing. Sometimes it does, sometimes it doesn't.

2) Do not skip the "Before you begin"[0] step. This is very important: 
if two packages share a namespace, either both or none of them must use 
python-support. Also, it's not enough just to convert them all to 
dh_python2: you must make sure (using Breaks or Depends relationships) 
that you cannot co-install an older python-support-based versions 
together with dh_python2-based ones.

I set up a page to track this kinds of issues in unstable[2] and 
testing[3]. Please note that I analyse only package contents, not 
relationships. The tracker is updated daily. (Any volunteers to file 
bugs?)
