#
#   USAGE: ./fix-filenames.py dir1 [dir2 ...]
#
#   Fix filenames and directory names, such that any "weird" character
#   is converted to an underscore.
#
#   A "weird" character is a non-alphanumeric character that is not
#   in the following list:
#	.-/[](),!_'&+#$~
#
#   For each directory given on the command-line, we fix the name of
#   *every* filename and directory name therein, recursing on subdirectories.
