From d36522d12d3e71958e50683a7eef43dc2a47d96d Mon Sep 17 00:00:00 2001 From: "mtklein@google.com" Date: Wed, 16 Oct 2013 13:02:15 +0000 Subject: dm is like gm, but faster and with fewer features. This is sort of the near-minimal proof-of-concept skeleton. - It can run existing GMs. - It supports most configs (just not PDF). - --replay is the only "fancy" feature it currently supports Hopefully you will be disturbed by its speed.
