# You need to manually download the IBM ILOG CPLEX Optimization Studio installer
# and place it into the same directory as this PKGBUILD, before you proceed.

# Note that CPLEX consistently refuses to run with recent Python versions and
# currently supports only versions 3.7 and 3.8. If you have one of those
# installed from the AUR, then the appropriate bindings will be installed.
