# TODO:
# - install includes for libs
# - nice output when configured
# - rename *.ui files to have the same filename as their implementation
#   e.g. instead of blahblahbase.ui use blahblah.ui
#   because it's more common in Qt4 
# Note on last point above by Tim Sutton - I prefer to have the base suffix
# as it indicates the ui generated class will be a base class for the widget.
