"""
Simple wrapper for ``docutils.core.publish_cmdline``.
During development, this should still be working.
Shortcomings are it cannot load settings-specs from transforms,
or perform processing only (without rendering).
It does not handle stores for transforms directly as Nabu does.
But, given that transforms could handle storage
initialization themselves, and that the Reader/Parser/Writer 'parent'
component can hold the settings-specs, should make it fairly easy to port
Builder code back to work with docutils.
