# The output then has helpful comments to allow you to easily transpile the scripting language into fast C, either with ChatGPT or manually.
# This is an invaluable resource to help you speed up code - in general.
# And the C functions in this library are very very fast and tested.
#
# I would appreciate someone making this script longer and better to acommodate for more languages.
# That would be a great contribution. Please email me <gregorycohennew@gmail.com>.

#
# It would be great if this took an OpenAI API key and then used GPT4 to transpile.
# Could do a hell of a good and safe job - because these functions are really obvious how they work and have exceptional error handling.
