# For OpenBSD, run using the following:
#
# scripts/release.sh 1 0 1 0 0 0 0 1 0 0 0 0
#
# For FreeBSD, run using the following:
#
# scripts/release.sh 1 0 1 0 0 0 0 1 0 1 0 0
#
# There is one problem with running this script on FreeBSD: it takes overcommit
# to the extreme. This means that some tests that try to create allocation
# failures instead make bc and dc crash. So running this script on FreeBSD does
# not work right now.
#
# For Linux, run two separate ones (in different checkouts), like so:
#
# scripts/release.sh 1 1 1 0 1 0 0 1 0 1 0 1
# scripts/release.sh 1 1 0 1 0 1 0 1 0 1 0 0
#
# Yes, I usually do sanitizers with Clang and Valgrind with GCC.
#
# To run sanitizers or Valgrind with generated tests, use the following:
#
# scripts/release.sh 1 1 1 0 1 0 0 1 0 1 0 1
# scripts/release.sh 1 1 0 1 0 1 0 1 0 1 0 0
#
# If this script fails on any platform when starting the Karatsuba test, check
# that Python is installed, especially if the error says something like:
# "karatsuba.py: not found".
