#28 to dotfiles modify gem path to strip trailing '/' so gem doesn't complain when you install gems to local that you don't have the local bin in your path
#26 to dotfiles adding ironman2 color scheme, which is like ironman but changes the constant style to still look different from other stuff when CursorLine is active
#25 to dotfiles add mako changes to accept call blocks properly
