    3 # awk script to convert a bdf file to C declarations in a form specialized
    4 # for the mouse cursors in syscons/scvgarndr.c.  Usage:
    5 #     awk -f thisfile < file.bdf < file.c
    6 # The accompanying syscons mouse cursor bdf file has specialized comments
    7 # which this script converts to details in the C declarations.
    8 # This is not a general conversion utility, but produces reasonable output
    9 # if the input is for a monospaced font of size between 9x16 and 16x16.
