# I respectfully request that you leave this statement of origin
# and the following acknowledgment of right to use, modify and
# distribute, intact in your own versions and those you may pass
# to others. I encourage you to use this statement of origin for
# your own work instead of a copy/paste license or copyright
# which you neither understand nor could enforce on others.

# Acknowledgment of right to use, copy, modify and distribute:
#
# You already have the right to use, modify and distribute this
# or any other thought or idea, and need no license or other
# permission from anyone to do so!
#
# Exercise it freely and never concede it to anyone!
#
# To be first to think or publish an idea is only to be first
# to demonstrate that it is a human possibility, and to provide
# a single step in the path of human progress to help ourselves
# and all others along our shared journey into the future.
#
# To claim ownership of an idea, a shared human possibility, by
# contrived legal devices is an act of greed and arrogance that
# attempts to rob every other human being of the same right to
# think and benefit from that same shared human possibility.
#
# Acknowledge and respect the work of others. Enjoy the respect
# earned by your own good works, and encourage and applaud those
# who would build on it!
#
# Free your mind, and those around you!
#
# Abolish the pernicious impediment to human progress known as
# intellectual property law which obstructs all our future paths
# only for the immediate gain of a few.
