# A helper script that operates sort of like Make, except it is
# a lot easier to read and write than a Makefile, and it works on
# any POSIX system.
#
# I chose to use a custom build script instead of using Make because
# it is much more portable and flexible. This script doesn't only
# handle building the code, it also handles formatting it, as well
# as generating patch files.
# If a .env file exists in the current directory, we load it.
# As Telodendria's build infrastructure relies heavily on
# environment variables, we allow users to specify their
# Telodendria-specific variables in a dedicated .env so they don't
# have to pollute their environment.
