###
# A Shell script to view the differences of a benchmark run,
# displaying the results in a framebuffer window.
#
# The following environment variables will modify how the view diff
# behaves (in case you're not running from a source distribution, for
# example):
#
#   PIX - the directory containing the pix files to be compare
#   PIXDIFF - the name of a pix diff tool
#   PIXFB - the name of a pix to framebuffer tool (e.g. pix-fb)
#
# Authors -
#  Mike Muuss
#  Christopher Sean Morrison
