    The default installation of imagemagick does not enable
    X11 support. plowshare uses the display command which does
    not work if X11 support is not enabled. To enable:
      brew remove imagemagick
      brew install imagemagick --with-x
    EOS

# This patch makes sure GNUtools are used on OSX.
# gnu-getopt is keg-only hence the backtick expansion.
# These aliases only exist for the duration of plowshare,
# inside the plowshare shells. Normal operation of bash is
# unaffected - getopt will still find the version supplied
# by OSX in other shells, for example.
