Quick installation of jigsaw

Hi all,
My problem is a bit complex:
I want to install Jigsaw allready configured in a special configuration
(with my own filters installed, with specific directoryResources etc.).
I can copy the Jigsaw directory as is with all the files, and pass the
root
variable to Jigsaw as an argument ( -root  \MyRoot ), but that is not
enough!
When Jigsaw instantiates it's resources it'll read the file
"http-server.props" in which the paths are not updated.
Is there a way to solve this?

I suppose what I need is one of two:
a. Somehow make jigsaw save the properties in the props file as a
relative path, not absolute.
b. Somehow change the properties before Jigsaw tries to initiate itself.

Any advice would be appreciated.
Thanx.
Yael Stav.
