From 03bfe08e1dd9faf48b06cb146bfa446575cde88a Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Fri, 20 Dec 2019 20:18:41 +0000 Subject: chore: Significantly restructure folder layout This moves the various projects from "type-based" folders (such as "services" or "tools") into more appropriate semantic folders (such as "nix", "ops" or "web"). Deprecated projects (nixcon-demo & gotest) which only existed for testing/demonstration purposes have been removed.
