They are not documented anywhere in our project materials (BTW they are documented in IEEE 1588), but you can simply run pmc interactively, trying the "help" command first. Then, try each command in turn. That will give you the sample outputs. Below, I include some notes, not really explained, but maybe better than nothing...
