YAMLish is a small subset of YAML that TAP producers may use to embed machine readable information in TAP diagnostics. See TAP diagnostic syntax for information about how YAMLish embeds in TAP.
Based on Data-YAML version 0.0.6 (Copyright (C) 2007, Andy Armstrong) but it is so thoroughly rewritten that I don't consider it derived work and I don't feel the need to resolve what "This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself." actually means.
