#  RubyRun bootstrap code.						    #
#										    #
#  To invoke RubyRun for Rails or a Ruby script, use command    #
#  line option -r.     							    #
#										    #
#     ruby -rrubyrun script/server <webrick>                    #
#                                                               #            
#  To remove RubyRun, simply remove the -r option.		    #
#                                                               #            
#  Generally no other code change is needed to run RubyRun.     #
