Subject: documentation from inside irb

Hi,

is there a way to call ri documentation from irb ?
Something like:

shell>irb
irb(main):001:0> help inspect
NameError: undefined method `execute' for module `IRB::ExtendCommand::Help'
         from (eval):4:in `instance_method'
         from (eval):4:in `help'
         from (irb):1
         from /usr/lib/ruby/1.8/rubygems.rb:1016
