Zeus is a simple server-side mod that controls downfall in the world, giving the ability to disable or enable rain and snow (precipitation) with a simple command.
Planned Features:
Client-side support... Maybe.
Ability to configure rain message via commands.
Permissions:
Currently not integrated with any permissions plugin.
The only requirement to use the commands is to be opped on the server.
NOTE: Zeus for Forge will no longer be actively developed, as I have ported it to bukkit, where it fits in better.
