abbrev-js

Just like ruby's Abbrev.

Usage:

var abbrev = require("abbrev");
abbrev("foo", "fool", "folding", "flop");

// returns: { fl: 'flop' , flo: 'flop' , flop: 'flop' , fol: 'folding' , fold: 'folding' , foldi: 'folding' , foldin: 'folding' , folding: 'folding' , foo: 'foo' , fool: 'fool' }

This is handy for command-line scripts, or other cases where you want to be able to accept shorthands.
