# This file tests the Bitmap class in the bitmap module
# It has to be called by passing two arguments:
#
#   - An input bitmap file
#   - An output bitmap file
#
# It converts the input bitmap to grayscale and save it to the specified
# output file. In addition, it creates a blank.bmp file in the current directory.

#
# A module for testing the classes in the bitmap module
