Hello! This mail is just to raise awareness of an alternative to "groff -mandoc", mandoc (née mdocml) at <http://mdocml.bsd.lv>. Disclaimer: I'm the project's lead. mandoc is a BSD-licensed, C implementation satisfying ONLY the BSD "-mdoc" manual format, and to a limited extent, the traditional -man. The system, as-is, handles the majority of BSD manuals, and does so considerably faster than groff. It still needs work and attention, largely testing, but it's getting there.
If you're interested in hacking or testing, do let me know! Thanks, Kristaps
