// Example:
//
//    package main
//
//    import (
//    	"fmt"
//    	"log"
//
//    	"github.com/prometheus/procfs"
//    )
//
//    func main() {
//    	p, err := procfs.Self()
//    	if err != nil {
//    		log.Fatalf("could not get process: %s", err)
//    	}
//
//    	stat, err := p.Stat()
//    	if err != nil {
//    		log.Fatalf("could not get process stat: %s", err)
//    	}
//
//    	fmt.Printf("command:  %s\n", stat.Comm)
//    	fmt.Printf("cpu time: %fs\n", stat.CPUTime())
//    	fmt.Printf("vsize:    %dB\n", stat.VirtualMemory())
//    	fmt.Printf("rss:      %dB\n", stat.ResidentMemory())
//    }
