resize command

[Daniel]

Is there any chance that you (or even I, if you can tell me where to look!!!) 
to allow the resize command to accept a percentage of total disk size?

I'm interested in using parted/linux to automate the installation of a windoze 
disk image onto hard drives, but the size of the drives varies from 4gb up to 
200gb, and to have a "resize 1 0 100%" command would be great. :)

I don't know how to program in c, but I really do learn quickly, any pointers 
on where to look would be appreciated. :)

Thanks,
