// WalkDirFunc is the type of the function called by WalkDir to visit

-// The path argument contains the argument to Walk as a prefix.

//
-// The directory and file are joined with Join, which may clean the

// The d argument is the fs.DirEntry for the named path.

// The error result returned by the function controls how WalkDir
