	#
	# Run the tests on various build configurations and various operating systems.
	#
	# In the Perl/perl5 repository all jobs are run by default.
	#
	# To enable the testing on a fork of the perl5 repository you first need to
	# enable GitHub Actions in 'Settings' -> 'Actions' -> 'General'.
	#
	# When actions are enabled then it will - by default - run the 'Sanity Check' job.
	#
	# Testing other build configurations is controlled by the 'Secrets' configured
	# in 'Settings' -> 'Secrets and Variables' -> 'Actions' -> 'Variables':
	# - DO_EXTENDED_TESTING: when this var exists and is set to a true value then
	# all build configurations are tested;
	# - CI_SKIP_SANITY: if set to a true value then most of the 'Sanity Check' job is skipped;
	# - CI_FORCE_LINUX: if set to a true value: run the 'linux' job;
	# - CI_FORCE_LINUX_I386: if set to a true value: run the 'linux-i386' job;
	# - CI_FORCE_INSTALL: if set to a true value: run the 'install' job;
	# - CI_FORCE_MACOS: if set to a true value: run the 'smoke-macos-catalina-xcode12' job;
	# - CI_FORCE_MSVC142: if set to a true value: run the 'windows-msvc142' job;
	# - CI_FORCE_MINGW64: if set to a true value: run the 'mingw64' job;
	# - CI_FORCE_CYGWIN: if set to a true value: run the 'cygwin' job;
	# - CI_FORCE_MINITEST: if set to a true value: run the 'miniperl' job;
	# - CI_FORCE_ASAN: if set to a true value: run the 'ASAN' job;
	# - CI_FORCE_PERL_UNICODE: if set to a true value: run the 'PERL_UNICODE' job;
	# - CI_FORCE_DIST_MODULES: if set to a true value: run the 'dist-modules' job;
	#
	# For the purpose of this workflow:
	# - 'true value': any value that is not false
	# - 'false value':
	# * empty string
	# * string containing only spaces (i.e. ' ')
	# * string containing only zeroes (i.e. '0', '0000')
	# * string containing only spaces and zeroes (i.e. '0 0 0 0')
	#
	# Example: if you only want to run tests on cygwin then you can set:
	# - DO_EXTENDED_TESTING=0
	# - CI_SKIP_SANITY=1
	# - CI_FORCE_CYGWIN=1
	# - (and all other CI_FORCE_... vars to 0)

	# "sanity_check" tests -Dusethreads without -DDEBUGGING
	# "linux-i386" tests -Uusethreads without -DDEBUGGING
	# All builds in the "linux" matrix test with -DDEBUGGING
	#
	# "sanity_check" sets `fetch-depth: 0` so that it does a git clone
	# with full history, and hence can run t/porting/cmp_version.t etc
	#
	# The git-related tests require full history, but we only need to run
	# them once (they aren't platform specific). Hence leave the others
	# with the default setting (1), which performs a shallow clone. In
	# these shallow checkouts, the git related porting tests skip (or
	# rapidly pass), but they won't fail spuriously.
	#
	# TODO - Now that we do not use secrets and instead use vars for the
	# control of which tests we run (due to the way secrets are elided
	# from the output), we can simplify the shell code below. The
	# following url includes discussion on what next steps we could take
	# to simplify the complexity of this code.
