##@ Requirements management

# When updating requirements, a few rules to follow:
#
# 1) Don't install more than one .pip file at once. Always use pip-compile to
# combine .in files onto a single .pip file that can be installed where needed.
#
# 2) Check manual pins before `make upgrade` to see if they can be removed. Look
# in requirements/pins.pip, and search for "windows" in .in files to find pins
# and extra requirements that have been needed, but might be obsolete.
