CommandHelper adds command aliases and repeat-last-command functions.
You need to have Maven installed (http://maven.apache.org). Once installed, simply run:
mvn clean package install
Maven will automatically download dependencies for you. Note: For that to work, be sure to add Maven to your "PATH".
We happily accept contributions. The best way to do this is to fork CommandHelper on GitHub, add your changes, and then submit a pull request. We'll look at it, make comments, and merge it into CommandHelper if everything works out.
