The latest script is here http://www.mediafire...dw9mvfd4b5s9bdi and the script is already included in any of my projects
For the setup, most portables only need a ppApp.ini included like this:
(only add or change data in red)<Title>
Title of Program
<Flags>
MakeInRoot = 0
MakeStart = 1
MakeSendTo = 0
MakeDesktop = 1
MakeQuickLaunch = 0
<StartMenuSourcePath>
Start menu folder name
<ppApp>
CommandLine = "Program.exe"
ShortcutName = "Program Name"
Description = "Description of program."
<End>
Some portables require a bit more setup (setups.cmd) so here is everything you need http://www.mediafire...x7wwiac645nia2i
Just add your portable program.exe alongside other files in this folder and add the folder to your ppApps directory at the root of any drive or included in PE* via script options.
*NOT recommended for a portable of this size!

I'm sorry I can't give you more help with the Ubuntu setup, I just don't use it and can't say what is possible or how well it will work. There are many sites dedicated to those things and remember, Google is your friend (well, not really but that's another discussion for another time)
