I'm happy to say Plan 9 is now a supported platform for the "Discount" tools for processing the Markdown format. One can grab Discount from its home page (http://www.pell.portland.or.us/~orc/Code/markdown/) & use an included & almost-normal mk routine to compile and install it. It builds in the APE environment, but no editing or other preparatory minor porting is required.
The odd step is a `mk config` stage, necessary to provide access to several Discount options provided only at compile time. Mk here is simply driving a typical Unix configure-make cycle beneath. Manual pages for the tool (markdown(1)) and the format (markdown(6)) are included. If you were using the Plan 9-specific `markdown` fork in /n/sources/contrib/josh, you'll probably want to switch over to Discount v1.4.3 or later. -Josh
