+# sudo gem install fpm -v 1.14.2
+# ./ssm-build-dual.sh (deb | rpm) <version> <iteration> <python_root_dir> e.g.
+# ./ssm-build.dual.sh deb 3.4.0 1 /usr/lib/python3.6
+# For SSM 3.4.0 and up.  Versions before that would technically work, but the changelog
+# then was in a Debian format that doesn't parse and fails hard if you want to build RPM.
