Save Patching
-------------
In order to efficiently get data in and out of running Factorio servers
and to provide custom interfaces Clusterio uses save
patching<sup>[1]</sup> to add code to the game. The save patching is
based on the built in
[event_handler](https://github.com/wube/factorio-data/blob/master/core/lualib/event_handler.lua)
library to Factorio and requires scenarios to be coded specifically for
it. Mods on the other hand work without modifications.
<sub>1: Before version 2.0 of Clusterio this was done at runtime
with a patcher called Hotpatch, but due to the difficulty in supporting
run time patching and the lack of documentation it was replace it with
save patching instead.</sub>
User Accounts
-------------
The master server creates and stores accounts for all Factorio users
that log into instances under its control. These accounts are used to
store per player data and authorize management of the cluster. By
default users accounts are assigned a Player role that gives a limited
read access to the cluster resources, and admins of the cluster can be
assigned an Admin role to get access to manage it.
