 ## "LowerIt"
 ##
 ## Original code found here:  http://www.linuxjournal.com/content/convert-filenames-lowercase ;  though this looks nothing like it.
 ## Modified by Maiya78 to change directory names, to work recursively, and to support unicode filenames on GNU systems.  I also copyedited the comments.  :3
 ##
 ## From the current directory, recursively convert to lower case all file and directory names
 ## Should ask for verification before overwriting an existing file.
