cmark [options] [file...]

cmark is the reference C implementation of CommonMark, a strongly specified and highly compatible variant of Markdown. It parses Markdown input and converts it to various output formats including HTML, XML, groff man pages, CommonMark, and LaTeX.
The parser is designed for correctness and performance, strictly following the CommonMark specification to eliminate the ambiguities present in the original Markdown description. This makes it suitable for applications that require predictable, consistent rendering across different tools.
cmark reads from files or standard input and writes to standard output, making it easy to integrate into pipelines. The --smart option provides typographic enhancements like curly quotes and em-dashes, while --safe strips potentially dangerous raw HTML from input.
