# This script renames folders and files. Letters with diacritical marks in French and in
# German are replaced with letters without diacritical marks.
#
#  1. By default, this script takes only one parameter, which is the absolute path of the
#     directory you want to scan through. In that case,if there is only one parameter, all
#     the letters in the big dictionary keys will be replaced. For example:
#           ~/rename_files.py /home/$USER/Images
#  2. If you choose to replace only one letter, you have to give two other parameters.
#     For example:
#           ~/rename_files.py /home/$USER/Images é e (it will replace é with e)
