About a3rig

a3rig builds and launches a complete local Arma 3 multiplayer test environment from
inside any HEMTT project: it runs the dev build, starts two game clients on separate
Arma profiles and a dedicated server, then tails the server log.

It reproduces HEMTT's mod resolution exactly, so every process loads the same mods in
the same order, and it checks the server config up front for the settings that silently
break a local rig.

What's new in 0.2.0

Install with winget:
