STFL is a library which implements a curses-based widget set for text
terminals. The STFL API can be used from C, SPL, Python, Perl and Ruby.
Since the API is only 14 simple function calls big and there are
already generic SWIG bindings it is very easy to port STFL to
additional scripting languages.

A special language (the Structured Terminal Forms Language) is used to
describe STFL GUIs. The language is designed to be easy and fast to
write so an application programmer does not need to spend ages fiddling
around with the GUI and can concentrate on the more interesting
programming tasks.
