# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

# zmqimage.py -- classes to send, receive and display cv2 images via zmq
#     based on serialization in pyzmq docs and pyzmq/examples/serialization

'''
PURPOSE:
    These classes allow a headless (no display) computer running OpenCV code
    to display OpenCV images on another computer with a display.
    For example, a headless Raspberry Pi with no display can run OpenCV code
    and can display OpenCV images on a Mac with a display.
USAGE:
