A simple program for setting up a gift exchange via email. Basically, me and some friends wanted to do a gift exchange, but we couldn't find a time to get together to draw names out of a hat. So I whipped this up to do it via email.
The program expects a file called people.json in the current directory.
People.json is an example of how the json should be
formatted. The program randomly assigns each person in people.json to
another person, and sends an email to the latter telling him he is getting
a gift for the former. You can specify a different file via the -input flag.
The program gets info about the email account to send from via two environment
variables: EMAIL_SENDER and EMAIL_PASSWORD. EMAIL_SENDER should be set to
a gmail email address, and EMAIL_PASSWORD to an "App Password".
