This directory holds code related to weekly snippets at the Khan Academy. Here is the functionality involved: 1) Reading snippets that are mailed to a particular email account, extracting the snippet-content and sender from the email, and storing them in a database. 2) Once a week, collecting the week's snippets from the database and sending them to interested users. 3) TODO(csilvers): A way of registering interest in snippets (perhaps only from certain people?) For now, all snippets are always sent to 'all'.
