const (

IsPathSeparator reports whether c is a directory separator character.

basename removes trailing slashes and the leading directory name from path name.

func basename(name string) string {

Remove trailing slashes

	for ; i > 0 && name[i] == '/'; i-- {
		name = name[:i]

Remove leading directory name

	for i--; i >= 0; i-- {
		if name[i] == '/' {
			name = name[i+1:]
			break
		}
	}

	return name
}

splitPath returns the base name and parent directory.

if no better parent is found, the path is relative from "here"

	dirname := "."

Remove all but one leading slash.

	for len(path) > 1 && path[0] == '/' && path[1] == '/' {
		path = path[1:]
	}

	i := len(path) - 1

Remove trailing slashes.

	for ; i > 0 && path[i] == '/'; i-- {
		path = path[:i]
	}

if no slashes in path, base is path

	basename := path

Remove leading directory path

	for i--; i >= 0; i-- {
		if path[i] == '/' {
			if i == 0 {
				dirname = path[:1]
			} else {
				dirname = path[:i]
			}
			basename = path[i+1:]
