+#!/usr/bin/python
+"""A Javascript minification utility.
+
+Users should not use this module directly; see the ``minify`` module instead.
+
+Minification squeezes out spaces and other characters not significant to
+Javascript.  This results in a shorter file size.
+
+Usage::
+
+    jsm = JavascriptMinify()
+    jsm.minify(input_file_object, output_file_object)
+
+Or if the Javascript is in a string (slightly less efficient)::
+
+    js = jsmin(js)
+
+This is a wrapper around ``JavscriptMinify``, so if your input and output are
+already file objects, it's more efficient to use ``JavascriptMinify`` directly.
+
+Originally written in C by Douglas Crockford, and ported to Python by Baruch

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
