Smi is a Simple Markup Interpreter / filter for simplified Markup dialect. smi can be fed text in Markdown, and return HTML output. smi can be fed HTML, and return the markup translated to entities. I use smi as a filter for devel/cgit to parse the README.md files, returning HTML output. I am also using it to markup wiki pages, for a git backed wiki. The use cases are limited only by your imagination. WWW: https://BSDforge.com/projects/textproc/smi/
