// Package hello provides an example to set up a relatively simple sarah.CommandProps.
//
// In this example, instead of simply assigning a regular expression to CommandPropsBuilder.MatchPattern,
// a function with a more complex matching logic is set via CommandPropsBuilder.MatchFunc to do the equivalent task.
// One more benefit of using CommandPropsBuilder.MatchFunc is that strings package or other packages with higher performance can be used internally like this example.
