Make optional spkg for gfsage

[kcrisman]

The EU "Molto" project has created a prototype of getting natural language to interface with Sage - see the starting webpage. This can be used as

• an interface
• an evaluation percent directive within Sage.

| Sage Version 4.8, Release Date: 2012-01-20                         |
| Type notebook() for the GUI, and license() for information.        |

sage: 2+2
4
sage: %english

  --> Switching to Gf <-- 

No autocompletion available
''
english: compute the sum of 2 and 2.
4
english: 

  --> Exiting back to Sage <-- 

sage: 

This is accomplished by some pretty minor changes in setup.py and adding a couple interface files in various places. We would not make this a standard package, ever, because the dependencies include Haskell and the grammatical framework GF.

So why not?

Nice. Can I suggest a tremendously helpful improvement? Can you print out the Sage code that is executed? That would help people learn the syntax and let them double-check the natural language parsing.

Well, their goal is somewhat different from ours. But maybe that could be an option in the main program, which we would enable by default in a Sage optional spkg.
