// Package execabs is a drop-in replacement for os/exec
// that requires PATH lookups to find absolute paths.
// That is, execabs.Command("cmd") runs the same PATH lookup
// as exec.Command("cmd"), but if the result is a path
// which is relative, the Run and Start methods will report
// an error instead of running the executable.
