The --help-outputs and --help are embedded in the README.md
To make it easier to read now options are enclosed in `` and the list of
outputs is sorted.
Implemented in a different way.
For all internal commands now we use Python bindings to fill the zones as
suggested by @arikrupnik in johnbeard/kiplot#11
For 'print_pcb' now we ask KiCad to do it before printing (needs v1.4.1)
The Python in the virtualenv doesn't know about pcbnew module.
When installed normally, this can be provided when setting up the
virtualenv. This lets you avoid messing about with PYTHONPATH.
The old instructions apply when KiCad is not installed to the
system (common when developing)
