RubyGFE goes Nautilus
I worte a nautilus script that uses RubyGFE to install files.
Here’s how it works:
Copy the NautilusGFE file to your ~/.gnome2/nautilus-scripts/ directory and make it executable.
Then select the files you want to install in nautilus (or on your desktop in GNOME), right-click and select Scripts->NautilusGFE

After that you can select for what gameyou want to install the files.
The installation begins after the last confirmation dialog.

In the end you can close the window or click OK to finish the installation. If the installation fails there will be RubyGFE like error dialogs.

Note: You need to have RubyGFE installed for this to work. If you have installed RubyGFE in a different location than /usr/share/RubyGFE you will have to modify the NautilusGFE script.
In line 3 you have to edit: RUBYGFE_INSTALL_DIR = path/to/your/rubygfe
