1. the pyc files aren't truly arch independent (they can be used cross-arch
but aren't identical), and
2. @version isn't used on PKG_ARCH=* ports so the py3 switch is tripping PLIST_DB
based on their docstrings. A lightweight markup language called
epytext can be used to format docstrings, and to add information about
specific fields, such as parameters and instance variables. Epydoc
also understands docstrings written in reStructuredText, Javadoc, and
plaintext.
