Area51 is an application that lets you look inside of  Unified Font Object (UFO) files among other things.

You can get the latest release version as a compiled application  here, you can check out the current development version with Subversion at  http://svn.typesupply.com/applications/Area51 or you can browse the source code here.

The application includes a manual under the "Help" menu.

Running From Source

If you wish to run Area51 from source, you will need to do a few things:

• Add a path to the Lib directory to a .pth file in your Python site packages.
• Install all dependencies:
  •  FontTools
  • Vanilla
  • DefconAppKit
  • defcon
  • Compositor
  • ufo2fdk
• When you compile the application, use "python setup.py py2app -A". This isn't required, but it will make it so that you can update the source code without recompiling the application.
