Subject: gems info showing up in PhoneBook object ??

I was just playing with the recent "command" utility. It has a single class.

class PhoneBook < Cmd ..... end

When I install this as a gem, and execute a breakpoint to inspect the
current PhoneBook in irb, and look at "self", I get all kinds of stuff that
is has not been declared anywhere in PhoneBook, as far as I can tell.

> self.class
#=> PhoneBook

> self
#=>
.... all kinds of stuff about gems as part of "self", many pages long.

      @has_rdoc=true,


I am guessing this is gems-related. But of course I could be doing something
really very dumb. Could someone shed some light? Is it from breakpoint/irb?

Also, what method does irb call to display an object? I tried defining to_s
and inspect on PHoneBook but it had no effect.

Thanks.
