{
// AFAICT, there is currently no library function that recursively removes a
// directory tree [i.e. a directory, it's subdirectories, and any other files]
// with a single call. Such a function needs to be custom built. PHP tools
// with which to do this:
// * 'unlink', 'rmdir', 'is_dir', and 'is_file' functions, will all take care
// of the file testing and deletion
// * Actual directory traversal requires obtaining directory / subdirectory
// lists, and here there is much choice available, though care must be taken
// as each has it's own quirks
// - 'opendir', 'readdir', 'closedir'
// - 'scandir'
// - 'glob'
// - SPL 'directory iterator' classes [newish / experimental - not shown here]
//
// The PHP documentation for 'rmdir' contains several examples, each illustrating
// one of each approach; the example shown here is loosely based on one of these
// examples
// Recursor - recursively traverses directory tree
