Complete command documentation (e.g. `help {commandName}`)

[ohadschn]

show commands displays some commands that don't seem to be documented anywhere, for example importTreeNow were documented somewhere.

Would be great to have something like a standard help {commandName}.

Yeah importTreeNow is considered kind of an implementation detail / developer only command so it's not documented for the wider public.

help {commandName} would be great!
