-## Modified by Maiya78 to change directory names, to work recursively, and to support unicode filenames on GNU systems.  I also copyedited the comments.  :3
+## By 'Maiya78' from the Paradox forums

 ## From the current directory, recursively convert to lower case all file and directory names
 ## Should ask for verification before overwriting an existing file.
 ## !BROKEN! Should also decapitalize Cyrillic, Greek, and other mixed-case scripts.
