+# If you are reading this because you came via code search, this script may not work for you,
+# but the idea does: Homebrew precompiled bottles are not compatible with older versions of
+# macOS, but Homebrew will also ignore the MACOSX_DEPLOYMENT_TARGET environment variable.
+# Take a look at this script and see how I am patching some .rb files to avoid ignoring that
+# environment variable.
+#
+# Note that brew install --build-from-source will not build from source the package dependencies.
+# This is why I build from source every package in the dependency tree as well, just in case
+# any of these packages is also a transitive dependency of mine, so that I can pack a dylib that
+# works with the given deployment target.
