"""Embeds standalone JavaScript snippets in C++ code.

Each argument to the script must be a file containing an associated JavaScript
function (e.g., evaluate_script.js should contain an evaluateScript function).
This is called the exported function of the script. The entire script will be
put into a C-style string in the form of an anonymous function which invokes
the exported function when called.
