+DESCRIPTION
+
+  The YUI Compressor is a JavaScript compressor which, in addition to removing
+  comments and white-spaces, obfuscates local variables using the smallest
+  possible variable name. This obfuscation is safe, even when using constructs
+  such as 'eval' or 'with' (although the compression is not optimal is those
+  cases) Compared to jsmin, the average savings is around 20%.
+
+  The YUI Compressor is also able to safely compress CSS files. The decision
+  on which compressor is being used is made on the file extension (js or css)
+
+GLOBAL OPTIONS
+
+  -h, --help
+      Prints help on how to use the YUI Compressor
+
+  --line-break
+      Some source control tools don't like files containing lines longer than,
+      say 8000 characters. The linebreak option is used in that case to split
+      long lines after a specific column. It can also be used to make the code
+      more readable, easier to debug (especially with the MS Script Debugger)
+      Specify 0 to get a line break after each semi-colon in JavaScript, and
+      after each rule in CSS.
+
+  --type js|css
+      The type of compressor (JavaScript or CSS) is chosen based on the
+      extension of the input file name (.js or .css) This option is required
+      if no input file has been specified. Otherwise, this option is only
+      required if the input file extension is neither 'js' nor 'css'.
+
+  --charset character-set
+      If a supported character set is specified, the YUI Compressor will use it
+      to read the input file. Otherwise, it will assume that the platform's
+      default character set is being used. The output file is encoded using
+      the same character set.
+
+  -o outfile
+      Place output in file outfile. If not specified, the YUI Compressor will
+      default to the standard output, which you can redirect to a file.
+
+  -v, --verbose
+      Display informational messages and warnings.
+
+JAVASCRIPT ONLY OPTIONS
+
+  --nomunge
+      Minify only. Do not obfuscate local symbols.
+
+  --preserve-semi
+      Preserve unnecessary semicolons (such as right before a '}') This option
+      is useful when compressed code has to be run through JSLint (which is the
+      case of YUI for example)
+
+  --disable-optimizations
+      Disable all the built-in micro optimizations.
+
+NOTES
+
+  + If no input file is specified, it defaults to stdin.
+
+  + The YUI Compressor requires Java version >= 1.4.
+
+  + It is possible to prevent a local variable, nested function or function
+    argument from being obfuscated by using "hints". A hint is a string that
+    is located at the very beginning of a function body like so:
+
+    function fn (arg1, arg2, arg3) {
+        "arg2:nomunge, localVar:nomunge, nestedFn:nomunge";
+
+        ...
+        var localVar;
+        ...
+
+        function nestedFn () {
+            ....
+        }
+
+        ...
+    }
+
+    The hint itself disappears from the compressed file.
+
+  + C-style comments starting with /*! are preserved. This is useful with
+    comments containing copyright/license information. For example:
+
+    /*!
+     * TERMS OF USE - EASING EQUATIONS
+     * Open source under the BSD License.
+     * Copyright 2001 Robert Penner All rights reserved.
+     */
+
+    becomes:
