A selenium server management script for node.js projects. Dug this relic up and updated line #7 so that it can act as a replacement for protractor's currently broken `webdriver-manager update`. Just pop this in your ./bin folder, make it executable, and run `./bin/selenium.sh install`. Jobs a good’un.
