# Use: "python ..\..\PyTools\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; used to catch old 
# uppercase file names created on MS-DOS (case matters on
# some platforms, when importing Python module files);
# caveats: this may fail on case-sensitive machines if 
# directory names are converted before their contents--the
# original dir name in the paths returned by find may no 
# longer exist; the allUpper heuristic also fails for 
# odd filenames that are all non-alphabetic (ex: '.');
