fsp - an 'fs' returning A+ promises (when).

A minimal fs that returns A+ promises (when). For each fs.xxx function, it adds an fs.xxxP returning promises.

Usage

Just fs = require('fsp') instead of 'fs' and omit the last callback parameter when calling a promise-returning fs.xxxxP function.

For example you can do

  var fs = require('fsp');

  fs.readFileP("some/file.txt", {encoding:'utf8'}).then(
    function(text){...}, function(err){}
  );

and all the other cool things you can do with promises.

Of course fs.readFile and fs.readFileSync are still available.

Note: fs.existsP works as expected - it resolves to boolean true / false if file exists or not (it never rejects - it uses fs-exists).
