Markdown extension for texts related to contract bridge and some half-finished system and convention descriptions.

The script does some preprocessing and passes the output to Markdown, so full Markdown syntax is supported. Apart from that, there are several additions:

Suit symbols can be written as !C, !D, !H and !S (as in BBO chat). These get converted to appropriate Unicode suit symbols and coloured. For consistency, !N is also provided and is converted to N.

Also, an en-dash can be written as --.

Footnotes are expressed by placing the text where their number should appear, wrapped in curly braces. For example:

This is some text {Footnote goes here.} with a footnote.

Space between the previous word the opening curly brace is optional and ignored. Full Markdown syntax is supported inside footnotes (except nested footnotes).

The render.sh script takes one argument, the (extended) Markdown input file. It writes its output to stdout. Example usage:

./render.sh docs/system.md > docs/system.html
