The sources for all squeakland installers are in a subversion
repository, the NSIS here:
http://svn.squeakland.org/installers/nullsoft/olpc/

I'm in the process of writing up some documentation but at least you
can see how the scripts work.

Hope they are helpful and please let me know if you need help.
