# Script for file name charset conversion. It includes
# options for renaming, changing charset, recursive file
# name expansion.
#
# Syntax:
#
# chnamecoding [options] (file|dir)
#
# Brief help on parameters:
# -r | --recursive - recursive
# -f | --charset-in - charset of the input filename
# -o | --charset-out - charset of output filename
## Script usage:
