Yes, 'perl qtguess.pl' and then 'perl generate.pl'.

I'm not sure if I actually need to run qtguess.pl, all it does is to
run various tests to see which options Qt was built with, and it writes
to the file qtdefines.

When you run the generate.pl script it starts a perl program called
'kalyptus' which uses the contents of the qtdefines file to skip any
methods/classes in the qt headers which were found to be missing from
the installed version of Qt. kalyptus generates the c++ code for the
smoke library from the qt headers, and you can compile them using qmake
to build a makefile from the project file 'qtsmoke.pro' in the smoke/qt
directory.

Here are the changes I made to generate.pl.in to create generate.pl and
get it to work:

$ diff generate.pl generate.pl.in
