CopyBlock is a markup language designed primarily for note taking. As an alternative to Markdown, it favours simpler semantics so that it is easier to parse, without compromising on (and indeed improving upon) readability of the source. It takes inspiration from Markdown, reStructure text, MediaWiki, AsciiDoc and Org.

Right now this page is just a simple demo so that I can send it to people to get feedback. A full specification and a reference implementation to come.
