# Some EPS files have broken bounding boxes. epstool will happily (via gs)
# calculate a new bounding box for us. The new bounding box is determined by
# the minimum extents of a) the draws objects and b) the paper boundary (by
# default letter).

# This script arranges to fix the bounding box in-place for the given file,
# choosing a new bounding box determined only by drawn objects. The
# -sPAPERSIZE=a0 is hackery to avoid paper size being an issue (A0 is pretty
# big paper).
