…When irb loads it somehow initializes all kinds of cool constants  
like $:, $LOAD\_PATH, $LOADED-FEATURES ETC…where could i get info on  
all of these things…the picaxe has some $… but not all $ENGLISH  
stuff…and to all thanks for answering my previous question ‘cannot  
require ‘date’ in irb’…it was already required when i looked into  
$LOADED-FEATURES…because my rubyopt=rubygems and thats oka…
