markdown - Convert Plain Text to HTML

Some YubNub commands let you convert a webpage to text. The 2t and html2text commands use the Asciinator hosted by Aaron Swartz. This service generates ASCII text of Markdown format.

John Gruber designed Markdown as a way to type up legible plain text with some formatting so it could be rendered later as HTML. Dingus is the online conversion tool that he created to show you how. Just use the cheatsheet to type in Markdown-formatted text and preview the corresponding HTML and source code.

The markdown command by Stephen Paul Weber offers a non-interactive way to render HTML. It does the opposite of html2text by converting a string or an entire page from Markdown text to HTML. I've added a page of text at Cl1p.net to show what you can produce with Markdown.

Example: markdown -url http://d.cl1p.net/markdown/

Markdown is used as quick way of adding formatting to comments on blog posts. I've heard that PHP Markdown is used as a WordPress plug-in. Blogger does not provide an option for Markdown at this time, but I guess that it can be implemented via a userscript.
