package reexec

import "github.com/dotcloud/docker/pkg/reexec"

Package reexec facilitates the busybox style reexec of the docker binary that we require because of the forking limitations of using Go. Handlers can be registered with a name and the argv 0 of the exec of the binary will be used to find and execute custom init paths.
