Callback parameters do not follow convention

[ryneo]

Your callback function parameters are reversed when compared to conventional pattern of callback(err, data){}. Wrapping the init function into a Promise erroneously returns an error since the data is being passed as the first parameter.

license.init('/path/to/package', function(licenseMap, err){
    if (!err) {
        console.log(licenseMap);
    }
});

ahh, I suppose it would be nice to be able to be compatible.

Can you send me an example of how you're using it with Promises?

[ryneo]

Here is an example of how I was using it. I used the Q promise library to wrap the callback into a promise.

var bowerLicense = require('bower-license');
var Q = require('q');

var licenseInit = Q.denodeify(bowerLicense.init);
licenseInit('path')
  .done(function (licenses) {
    // Do stuff with licenses
  });

I see, I will accept a PR if you make one

Its not an original goal of this project, but supporting it doesn't seem difficult at all

Thanks!
