Done! Enjoy your new sub! If you're happy with your sub, run:

    rm -rf .git
    git init
    git add .
    git commit -m 'Starting off $SUBNAME'
    ./bin/$SUBNAME init

You can remove the example when you no longer need it:

   rm -r libexec/${SUBNAME}-example

Made a mistake? Want to make a different sub? Run:

    git add .
    git checkout -f

Thanks for making a sub!
