Markdown to HTML: script compatible with WSH

There's a Markdown-to-HTML converter at [Pagedown][1] project (JS script).
My question is: how can I adapt this JS script to WSH (Windows Script Host) usage? I need e.g. js script which can be called by WSH command line:

cscript.exe md_to_html.js c:\test\aa.md

I didn't find such page in google.

Create WSF-file named **pagedown.wsf** with the following script

<!-- language: lang-html -->

<job>
<object id="Stream" progid="Adodb.Stream" /> <!-- utf-8 documents support -->
<script language="jscript" src="Markdown.Converter.js" />

<script language="jscript">
Stream.Charset = 'utf-8';
Stream.Open();
Stream.LoadFromFile(WScript.Arguments.Item(0));

var text = Stream.ReadText();

WSH.Echo(new Markdown.Converter().makeHtml(text))
</script>
</job>

and use it with **cscript.exe**

cscript //Nologo pagedown.wsf input.md > output.html

In case of troubles with ADODB try to download and install it from [here][1].
