From 328a7514573bcb268c813a977153a8995bf52698 Mon Sep 17 00:00:00 2001 From: Nico Weber Date: Mon, 11 Mar 2019 20:23:40 +0000 Subject: Remove esan. It hasn't seen active development in years, and it hasn't reached a state where it was useful. Remove the code until someone is interested in working on it again.
