	# WARNING: Please read on bumping or applying patches!
	#
	# There are two circular dependencies to be aware of:
	# 1)
	#	if we're bootstrapping configure and makefiles:
	#		libxcrypt -> automake -> perl -> libxcrypt
	#
	#   mitigation:
	#		toolchain@ manually runs `make dist` after running autoconf + `./configure`
	#		and the ebuild uses that.
	#		(Don't include the pre-generated Perl artefacts.)
	#
	#	solution for future:
	#		Upstream are working on producing `make dist` tarballs.
	#		https://github.com/besser82/libxcrypt/issues/134#issuecomment-871833573
	#
	# 2)
	#	configure *unconditionally* needs Perl at build time to generate
	#	a list of enabled algorithms based on the set passed to `configure`:
	#		libxcrypt -> perl -> libxcrypt
	#
	#	mitigation:
	#		None at the moment.
	#
	#	solution for future:
	#		Not possible right now. Upstream intend on depending on Perl for further
	#		configuration options.
	#		https://github.com/besser82/libxcrypt/issues/134#issuecomment-871833573
	#
	# Therefore, on changes (inc. bumps):
	#	* You must check whether upstream have started providing tarballs with bootstrapped
	#	  auto{conf,make};
	#
	#	* diff the build system changes!
