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.
