The idea being that if you are working on a project and want to switch between computers, say desktop at the office and laptop at home, this script makes it easy to transfer the relevant data back and forth between computers.
You can do this as many times as you want for as many projects as you have, just keep the initial install package to run from each time, (or re-download it from here).
You can also uninstall this app using the uninstall.sh script found at ~/bin/{project name} (where project name is whatever you named it when installing).
The uninstall script found in the 'installed' location is specific to that instance.
That'll be me I guess, Peter Green though calling it development seems to be pushing it a bit for a bit of bash scripting! It's the nearest I have got though ;-)
