I'm not making new dialogs, just extending the existing ones.

I'm already using that class during the build process. I just needed
to extend the wizard page to get a few options to create the
environment. The environment variables are set using a bash script,
and the location of the script is what I need to get from the user.

Ah, I'll take a look at that method.

I was afraid someone would suggest that. :P I guess I could do some
"splicing" to remove the page after it was loaded. I'll play a bit
around with it.
