Previously we put cli.py into the common lib folder, which caused the
API to be regenerated and rebuilt whenever we changed code that will
only affect the CLI, causing terrible turnaround times.
Now the dependency is fixed.
That way, all information can be placed within a single markdown file
per method call. This will keep loading times low while maximizing
usability.
That way, it's comparable to the API documentation, which is most
detailed on a per-method basis as well.
That way, a single huge markdown file containing documentation for
commands and methods can be split up into multiple files for
individual inclusion in mkdocs.
It's done by a post-processor which is loaded by mako-render, providing
access to the entire context. Said processor may also drop results
altogether and thus prevent files to be written that have been split up
by it.
