The Ruby version 1.6.2 download for PCs

   ruby-1.6.2-20001218-i386-cygwin.tar.gz 

is missing the irb.bat file that was provided in the
preceding version 1.6.1 binary download.

To easily run irb at the command line, PC users may wish to
use Notepad to create an irb.bat file and place it in their
c:\ruby\bin directory. The contents of the file will be:

@echo off
C:\ruby\bin\ruby C:\ruby\bin\irb %1
