"""Extracts messages from .js files into .json files for translation.
Specifically, lines with the following formats are extracted:
/// Here is a description of the following message.
Blockly.SOME_KEY = 'Some value';
Adjacent "///" lines are concatenated.
There are two output files, each of which is proper JSON. For each key, the
file en.json would get an entry of the form:
"Blockly.SOME_KEY", "Some value",
The file qqq.json would get:
"Blockly.SOME_KEY", "Here is a description of the following message.",
Commas would of course be omitted for the final entry of each value.
