# TODO: enforce c99
# eventually add -Wextra

# Personal makefile notes:
# '$@' gets replaced with the target name
# '$^' gets replaced with the target's dependencies (to right of target name)
# For more, check out https://youtu.be/G5dNorAoeCM

# Note: I understand this makefile is not as optimal as it could/should be
