I was just wondering what the recommended check-out command
for "test-users" would be. With
 svn co https://svn.sourceforge.net/svnroot/matplotlib/trunk matplotlib
I get the whole tree:
 56K ./.svn
 280K ./CVSROOT
 69M ./course
 31M ./htdocs
 50M ./matplotlib
 194M ./toolkits
 39M ./users_guide
which is about 381 MB...
The answer seems to be this one:
 svn co https://svn.sourceforge.net/svnroot/matplotlib/trunk/matplotlib \
 matplotlib
Best, Arnd
P.S. For the above command I get the following:

While it builds everywhere, it causes unresolved symbol errors on all
non-HP/PA platforms :(

If the breakpoint is in a event handler, or other code in the gui thread 
there is no way to get back into the main loop without returning from 
the event handler, although it can be simulated with a wx.EventLoop 
instance, but that also needs to be running in the gui thread. So there 
really isn't a way to do it if you need to stop in the gui thread.
