Scripting interactive console menus...

What scripting language / extensions would be best to use to write an
interactive console text menu system. I am thinking of something like
the kernel's menuconfig only in a scripting language rather than C. Any
idea's ?

A cool hack does this. It's like a ninja: It won't tell you how cool it
is, you just look at it and be like, ``wow, that's cool''.
