It’s still early in development but the idea to allow for extensions for difference games and mods for more specific customisation.
Each folder represents a different game. At the moment it’s just Minecraft, but I’ll be adding more over time.
Mods represent a way to customise based on the mods you have installed without overwriting core code. The mod_vanilla is the default and has the basic hook methods for pre-processing logs, processing log lines, post-processing logs and querying the server. Additional mods can be added to target specific log parsing or queries (see mod_spigot, mod_mineversechat)
