# Instructions:
# - if you edit a command running python, make sure to
#   write . $(VENV) && python3 -- this sets up the virtual environment.
#   if you just write "python3 foo.py" without the ". $(VENV) && " before,
#   the libraries will not be loaded during run time.
# - all targets running python somewhere should have venv/bin/activate as a dependency.
#   this makes sure that all required packages are installed.
# - Disable bibtex etc. targets by setting NOBIB=true (for debugging etc.)
#   (e.g., make -j4 NOBIB=true)
