What would you like to do?
Extracts all quoted text from a file, and generates a word count. Meant to be run by Node.
/*
* Extracts all text in double quotes from a given text file, as well as
* coffeescript-style fenced quote blocks ("""). Outputs an approximate word
* count for all of the content in quotations.
*
* Runs on Node.js, but doesn't require any npm modules.
