-These themes were not created by me. I found them all over the net.

-Converting Xcode 3 themes
------------------
-The Ruby script (which is public domain) was found [here] [script] and is being included for convenience. To use it, do the following:
-
-1. Install the plist gem with `sudo gem install plist`
-2. Run the script with `./dvtcolorconvert.rb ~/Library/Application Support/Xcode/Color Themes/yourXcode3Theme.xccolortheme` (this directory won't exist unless you've made custom themes for Xcode 3, which could be as simple as duplicating an existing theme).
-3. The converted theme will be in the same directory as the original.
-4. As with installing the other themes, simply copy the converted theme to `~/Library/Developer/Xcode/UserData/FontAndColorThemes/`.
-5. Restart Xcode 4.
