Desktop Workshop Installation Framework

Question

In an effort to keep the Desktop Workshop thread clean (i.e.: theme requests only), I'm moving the thread for those helping test the prototype installer I've put together for my themes here. If you are helping with the tests, please post ideas, bugs, constructive criticism and the like here. For those of you just joining us, starting with the RatLook theme, all my themes will have an install script with them. Use of this script is by no means mandatory (in fact, the script is still very much a prototype). However, I would greatly appreciate it if you would at least give it a try and send me some feedback.
The syntax of said installer is simple:
$ ./install = install theme
$ ./install -r or ./install --remove = remove theme
When the installer is run, the script will do the following things:
   * Check the computers resolution and warn the user if it does not match the themes optimized resolution
   * Verify that any needed dependencies are installed
         * The installer itself requires gtk-theme-switch2 and either feh or nitrogen
         * Themes usually require tint2 and conky
   * Backup the users current wallpaper and openbox config
   * Install any necessary fonts to $HOME/.fonts/   
   * Automagically copy the necessary configs to a standardized location ($HOME/.config/openbox/workshop/<theme>)
   * Install necessary theme files to $HOME/.themes/
   * Activate the theme
When the uninstaller is run, it removes the installed files and restores the backed up configuration.
For those who may want to take a look at the installer without actually having to download a theme, here is the current code.

Answer 1

I haven't tried this out, but just a couple of days ago I was thinking about something similar, mostly after seeing some of the cool desktops posted on Lifehacker. I was wondering how feasible it would be to come up with a system that lets you save the look of your desktop (window manager, wm theme, gtk, fonts, conky, wallpaper, etc), to say a tar.gz file, and then restore it at a later time. The real problem is handling exactly how much you want saved, right down to settings hidden away in gconf for example, or just the fact that everyone uses different window managers. But it would be bloody cool to combine it with a small pygtk app that shows different theme packages with a screenshot and description and allows you to change it with a click and a logout/login. Unfortunately it's probably a fair bit too complicated to pull off without some serious hacking.
Edit: That sounds awesome Ghost, I decided to edit my post rather than posting a reply in order to keep the thread clean. I'm probably being over cautious
