# This is part of my .pryrc. 
# I put this at the section where I load Rails stuff, so I can use Pry instead of IRB 
# for my Rails Console sessions

# Once this is loaded, just run the display_routes method from the console to see the same output that rake routes displays.
# I think it's better because I always leave a Rails console session running :)
