[aur-general] Python-3.x transition with python-2.7 update

[Allan McRae]

Hi all,

Here comes a rebuild so large that our TODO list had trouble handling 
it!  Hopefully all packages are now in the rebuild list....  At a total 
of 518 packages long, it puts the combined libpng/libjpeg rebuild to shame.

Python-2.7 has been releases and will be the last 2.x official release 
of python.  So it is time to switch to python-3.x as our /usr/bin/python 
and python-2.7 as our /usr/bin/python2.  See 
http://wiki.archlinux.org/index.php/DeveloperWiki:Python_Todo_List for 
all the details about how to achieve this.

It is actually not that hard.  I had a system converted when python-3.1 
was released as a test run.  The main key is to build packages in a 
clean chroot so that they detect and point their files to 
/usr/bin/python2.  Some packages are stupid and require a sed at the end 
of packaging to fix that.

Because this rebuild is crazy stupid, I would like to plan when it is 
going to occur.  We will need to clear out [testing] as much as possible 
over the coming week or two (what is happening with perl...).  Also, a 
new KDE is a the beginning of next month so I would not want to conflict 
with that.  Any other major rebuilds on the way?  Should we do this in a 
separate repo?
