# Use: "python ..\..\Tools\fixnames_all.py".
# find all files with all upper-case names at 
# and below the current directory ('.'); for each, 
# ask the user for a new name to rename the file to;
# I use this script to catch old uppercase file
# names created on MS-DOS (case matters on some
# platforms, when importing Python module files);
# notes: 
# - the os.path.walk function may be better here,
#   since we visit every file: see fixnames_all2.py;
# - we could instead blindly covert all-upper names 
#   to all-lower too, but that's a bit dangerous so
#   convertOne suggests an all-lower default name;
# - this may fail on some machines if directory 
#   names are converted before their contents (the
#   original dir name in the path returned by find
#   no longer exists), but I've only run this on 
#   Dos/Windows where case doesn't matter in the 
#   directory path, for os.rename calls (ymmv);
# - the allUpper function's heuristic fails for odd
#   filenames that are all non-alphabetic (ex: '.');
