+If you want to check out what GitWeb would look like for your project, Git comes with a command to fire up a temporary instance if you have a lightweight web server on your system like `lighttpd` or `webrick`.
 On Linux machines, `lighttpd` is often installed, so you may be able to get it to run by typing `git instaweb` in your project directory.
 If you're running a Mac, Leopard comes preinstalled with Ruby, so `webrick` may be your best bet.
 To start `instaweb` with a non-lighttpd handler, you can run it with the `--httpd` option.(((git commands, instaweb)))
