How do I open the Git GUI from a command window?

How do I open the Git GUI from a command window? I'm using Windows 7. I've
tried running this:
"C:\Apps\Git\libexec\git-core\git-gui"
but that's not a windows script. When I right-click on a folder, I see an
option that says, "Git GUI Here". When I click on that, the Git GUI opens
up. I want to do the same thing from a command line.
