This is a very simple Rack-Compliant HTTP Server based on GServer. See the examples directory to see how to run a couple of small rack apps. To run a Rails 2.3 app, in the root of your Rails app, run these commands:

$ gem install g_thang
$ script/generate g_thang
$ script/g_thang

The purpose of this server is just to illustrate how Rack and GServer work.
