Reddit-SMS-Notifier.py

"""
Reddit-SMS-Notifier.py

Monitors a subreddit for new posts matching a search term, and sends an SMS
alert via Twilio whenever a matching post is found. Keeps a local record of
already-seen post IDs (idArray.p) to avoid duplicate notifications, and logs
activity to a timestamped file in ./logs/.

Requires: praw, twilio
Fill in your Reddit API credentials, Twilio credentials, and search settings
in the __main__ block before running.
