Also remember to update configure.in to have it generate your Makefile.
Updating the Win32 makefile.msc's is also nice.

I do believe Chronogram is a good example.

AAAHHHHH!!!

Well, I guess we deserve that for not making a good list property yet.
But the code you add using non-deprecated methods will surely be useful
when we do a generic list property.  Much better than copying the UML
code.
