Using Crystal-lang to send SMS messages via Twilio

Sending SMS with Crystal

1. You will need to have an account at Twilio. Sign up for a free account at https://www.twilio.com/try-twilio
2. For convenience, I am using RVM (Ruby Version Manager) to easily load environment variables when I enter the project directory. Feel free to load the environment variables by other means though. If using the RVM approach, copy .ruby-env.sample to .ruby-env and put in your Twilio creds and phone number.
3. Run with crystal sms.cr or build the executable with crystal build --release sms.cr and run with ./sms
4. If run without arguments TO_PHONE is set to the environment variable TO_PHONE, and message is set to an internal default.
5. To quickly send a message to a phone number (this requires crystal build from above) run for example:

./sms 8171234567 "Waas Up?"
