Deploy a Bottle app on Heroku

gistfile1.sh

mkdir heroku
cd heroku/
virtualenv --no-site-packages env
source env/bin/activate
pip install bottle gevent
pip freeze > requirements.txt

cat >app.py <<EOF
import bottle
import os

@bottle.route('/')
def index():
    return "Hello World"

bottle.run(server='gevent', port=os.environ.get('PORT', 5000))
EOF

chmod a+x app.py

echo 'web: app.py' > Procfile
echo 'env/' > .gitignore

git init
git add .
git commit -m "Initial commit"

heroku create
git push heroku master

Apparently for gevent you need to use gevent.monkey.patch_all(). Also may be there was something I did wrong but I think you need to add host . Because as I could see heroku ran just a local server with this.
I have added some revisions here
