# Torndb is a very thin wrapper around MySQLdb that makes it even easier to use MySQL.
# Because it is very light, one can just go through the one-file python source
# to learn how to use it.

# Installation: pip install torndb
# Official doc: http://torndb.readthedocs.org/en/latest/
# Source: https://github.com/bdarnell/torndb/blob/master/torndb.py

JavaScript.load("/javascripts/something.js");


// With callback (that’s the good thing):

JavaScript.load("http://www.someawesomedomain.com/api.js", function() {
  API.use(); // or whatever api.js provides ...
});
