/*A command-line tool for setting the mouse speed on Windows machines.
This comes in handy when using different mouses (e.g. at work and at home)
that require different speed settings.

Dependencies: sys package (go get golang.org/x/sys/...)

GoAndWait

• Tests code generation using ccg (reusee/ccg).
• Encapsulates a concurrency pattern.

GoAndWait wraps a common concurrency pattern into a generic function:

• The items of a list shall be processed concurrently
• The main routine must wait until all items have been processed

package main

import "fmt"

// The interface.
type interf interface {
	Method(string) string
}

// A struct.
