# Usage: draw_pieces.sh {OUTPREFIX} < {INFILE}

# Reads from standard input a file produced by the povray macro "write_pieces".
# Arranges those pieces in standard sheets of material to cut out.
# For each sheet with sequential index {ix}, produces an EPS file 
# "{prefix}_{ix}.eps" with a drawing of the sheet and how the pieces 
# are to be cut out.  Also produces a text description "{prefix}_layout.txt".
