# 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 material {mat}, thickness {thk}, and sheet index {ix}, writes a PDF file 
# "{prefix}_{mat}_{thk}_ix}.pdf" with a drawing of the sheet and how the pieces are
# to be cut out.

# !!! For now just sorts and prints the pieces !!!
