cURL typically comes pre-installed.
For Mac use homebrew and one of:
brew install wget
brew install curl

Optionally set up virtualenv:
virtualenv --no-site-packages venv
source venv/bin/activate
Install libraries needed for fast XML processing and Python extensions. For Ubuntu/Linux:
apt-get install python-dev libxml2-dev libxslt1-dev
Install Python packages:
pip install -r requirements.txt
python changewithin.py
Assuming the above installation, edit your cron table (crontab -e) to run the script once a day at 7:00am.
