The qxembed example should be fixed in the latest snapshot, unless I missed 
something. I'll check it again - might have gotten messed up with version 
control. I missed the enum in the systray example, so I'll check that out. 
I'll go through the templates too.

The basic/ directory is the annotated/ stuff without all of the comments. That 
install location sounds find to me if it's findable by users. I use them to 
start off programs, and the comments are annoying, but hopefully they're 
helpful to newbies.

The problem with KIconThemeDir is that it's a forward declaration of a class 
that's defined in the cpp file. sip doesn't use the cpp files when compiling, 
and I've yet to find a way to get sip to ignore this. The fix is to provide a 
kicontheme.h that doesn't forward declare the class, and that's what's 
supposed to be in extra/kde332. It's private, so Python users can't access it 
anyway.

Unfortunately, I just copied the file over and forgot to modify it - just 
comment out the two lines that refer to KIconThemeDir in that h file (or copy 
the kicontheme.h file from extra/kde330 --  /kde331 is wrong too).  My 
systems don't have a problem with it any more, so I tend to miss it unless 
other people notify me.

Lastly, run importTest.py (top level directory) with the gcc-3.4 compiled 
version. I don't have gcc-3.4 and there are some reports of problems. If 
there's a problem, some of the modules won't import.

I'll get the fixes above into the next snapshot, which will be available in a 
day or two. If Phil is away, it won't get posted to the riverbankcomputing 
site immediately, so let me know if you want me to mail it to you. It's about 
1.2MB uuencoded for mail.

Thanks for the feedback!
