Before reading the code, see docs/info.md.

Clean and easy to use commands system

Example code:

List of notable features:

• Low-boilerplate argument handling system that supports arguments of various types, and optional arguments. Automatically generates an error if one of the args is invalid (eg, specifying a team that does not exist, or an ambiguous player name).
• Intellisense for the arguments (The IDE will see args: ["team:team?"] and correctly type args.team as Team | null)
• Callback-based menu system with builtin permission safety
• Command handlers are provided with the command's usage stats (how long ago the command was used, etc)
• Tap handling system
• Permission handling system
• Easy failing with fail() and its associated pattern
• Automatically allows using a menu to resolve arguments left blank
