+JSON.minify() minifies blocks of JSON-like content into valid JSON by removing all 
+whitespace *and* comments.
+
+JSON parsers (like JavaScript's JSON.parse() parser) generally don't consider JSON
+with comments to be valid and parseable. So, the intended usage is to minify 
+development-friendly JSON (with comments) to valid JSON before parsing, such as:
+
+JSON.parse(JSON.minify(str));
+
+Now you can maintain development-friendly JSON documents, but minify them before
+parsing or before transmitting them over-the-wire.
+
+Though comments are not officially part of the JSON standard, this post from
+Douglas Crockford back in late 2005 helps explain the motivation behind this project.

+
+"A JSON encoder MUST NOT output comments. A JSON decoder MAY accept and ignore comments."
+
+Basically, comments are not in the JSON *generation* standard, but that doesn't mean
+that a parser can't be taught to ignore them. Which is exactly what JSON.minify()
+is for.
+
+The first implementation of JSON.minify() is in JavaScript, but the intent is to
+port the implementation to as many other environments as possible/practical.
+
+NOTE: As transmitting bloated (ie, with comments/whitespace) JSON would be wasteful
+and silly, this JSON.minify() is intended for use in server-side processing
+environments where you can strip comments/whitespace from JSON before parsing
+a JSON document, or before transmitting such over-the-wire from server to browser.
