 This repo contains both automated tests for node and manual tests for the browser. The automated tests can be run using mocha (type `mocha` in the root directory). To run the manual tests:
 
 * Build the tests using `build.js`
-* Visit `amd-test`, `browser-test`, and `browserify-test` using the HTTP protocol (`python -m SimpleHTTPServer` can be used on OS X)
-  * The test `browserify-test` currently isn't working due to a bug with browserify. See pull request #66 for details.
