info -help expectations?

info -help expectations?

[Phil Muldoon]

I have the info command more or less working so:

(fhpd) info
auxv - Print process auxiliary
debuginfo - Displays debuginfo install paths of a process.
maps - Print process maps
regs - print registers

and

info <subcommand>

works as it should. But MultiLevelCommand interprets:


(fhpd) info -help
Error: Unknown command: -help

As a command. There is a help function, but that seems never to be called.

Regards

Phil

Hmm; should this print an error (missing command) or the list, and -help 
print the list?

Since there's an info command what were <<regs vector>> et.al. can 
probably be made <<info vector>> et.al.

nice edge case; does the converse <<help info>> work?  Like "run", the 
class probably needs an explicit check for -help; option parsing would 
be overkill.

I think typing info and no command, it should automatically print the 
info help - it is a more friendly touch. All fodder for discussion 
though, in the next workflow meeting in the new year.
