        # Dir.each_child

(from ruby core)
---
    Dir.each_child( dirname ) {| filename | block }                 -> nil
    Dir.each_child( dirname, encoding: enc ) {| filename | block }  -> nil
    Dir.each_child( dirname )                                       -> an_enumerator
    Dir.each_child( dirname, encoding: enc )                        -> an_enumerator

---

Calls the block once for each entry except for "." and ".." in the named
directory, passing the filename of each entry as a parameter to the
block.

If no block is given, an enumerator is returned instead.

    Dir.each_child("testdir") {|x| puts "Got #{x}" }

*produces:*

    Got config.h
    Got main.rb
