"""
Port Knocking with scapy example.
Knock on port 42304
Knock on port 53768
Knock on port 3297
HTTP request to port 19760

# 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.
