It is basic, read-only, implementation of ERTS system information filesystem. So far the implementation contains 3 directories: - `processes` with list of processes containing basic process information - `applications` with list of loaded applications as well as basic information about these - `system_info` with information about ERTS Future improvements should add `memory` and `statistics` paths as well and things like removing process directory as a way to kill process or pseudo-file that will allow sending messages to processes.
