CommonMark parsing and rendering program
cmark is the C reference implementation of CommonMark, a rationalized version of Markdown syntax with a spec.
cmark parses almost as fast as sundown and hoedown (but safer and less buggy), about 3 times faster than discount, and about 100 times faster than kramdown and pandoc. Memory consumption is on par with sundown and about 10 times less than pandoc.
cmark outputs HTML, groff man, LaTeX, CommonMark, and a custom XML format.
Markdown is a lightweight markup language with plain-text-formatting syntax.
This package provides a command-line program (cmark) for parsing and rendering CommonMark documents.
