@phillipskevin I checked things are working - if you want to review before closing.

• https://github.com/bitovi/querystring-parser/tree/v0.4.0
• https://www.npmjs.com/package/@bitovi/querystring-parser

note: The "Tests" badge in the npm readme won't work as long as the github repo is private.

Looks good to me. Any reason we shouldn't make the repo public?

[michael-dean-haynie]

I can't think of any reasons. People could already inspect the npm package if they wanted. Making the repo public also lets them see the issues and git data ... but that doesn't seem like an issue.
