Thank you!

You've saved the world for a lot of casetta users :-)

And how py2exe deal with non-standard python modules, like the PIL? The
casetta packages could be 'compiled' like the PIL, isn't it?

(And now we know why Windows programs needs a full CD-Rom or DVD-Rom to
be distributed... and not only less-than-500-ko-packages.)

I never used it, but I heard a lot of great things about it.

Just about the GTK installation from the Gimp: I've read (but never
check it) that the Gimp doesn't use the libglade, and then the GTK
distributed with the Windows installer of the Gimp hasn't the libglade
support. Does your installer check the libglade support? (Or perhaps I'm
wrong about libglade and the GTK of the Gimp.)

This is very good, the choice of component is a good features (most
users will never use the cli), and the look of the installer is far
better than the distutils one.

Good idea!

I haven't fully tried those installer (I've only a win98 SE under qemu,
which need GTK 2.6, and Wine), but I seems to work.

The only drawback it's that need a windows (or windows compatible)
system. Actually, I've a script that build the source archive and the
windows (distutils) installer, all on my GNU/Linux system.
Maybe it's possible to use Wine to use the NSIS compiler.

All it's clear!

It's not me, with my two left hands in inkscape (see the gasetta icon -
which re-use an icon from the KDE icon set), who'll judge your work! For
the moment, your installer provide a smarter setup than the distutils
one, and its what windows users wants.

I've no idea about it.

I'll fix it in the repository, and rebuild the source archive and the
distutils installer. Non-windows packages doesn't need to be updated,
they doesn't use this script. Because it's not in the code of casetta,
I'll not upgrade the version number.

If you think yours installers are ready, I can upload them on the
download repository, and update the website. I'll also made an archive
with the source of the installer, and upload them in the svn repository
(in branches/win-installer or something like).
If you want, I can get you a write access to the repository.

What's your opinion about that?

Thank you a lot for this great contribution!

Cheers,
