# When testing a rails website on my local development machine, I found my 
# Parallel's VM wouldn't load 0.0.0.0:3000, 127.0.0.1, or localhost:3000.  
#
# So I tried using my computers IP address and voila.  I thought I'd hone
# my bash chops a little and extract the IP address with the port number
# concatenated to it.  This command puts that on the clipboard so I can just
# paste it into IE so I could browser test. 
#
# NOTE: the pbcopy command is Mac specific.
