    LFF utilities

    These should work OK on DEC-MIPS, DEC-VAX, and SUN architectures.
Anything else will require editing include/pixlib.h to get the correct
byte order defined. I haven't played with this code since 1985, aside
from the minor hacking to make it compile now.

    'make' should produce several programs:

	bin/lffhdr	- print header of LFF file in text format
	bin/lfftoppm	- convert LFF file to PPM
	bin/mklffhdr	- generate the header of an LFF file

	[and some others, see the man pages]

    You can try them out as follows:

	$ lffhdr gaspra.lff
	----------
	gaspra.lff
	----------
		Version:     1
		Label:
		Height:      100
		Width:	     143
		Tile Height: 100
		Tile Width:  143
		Format:      rgb
		Storage:     dump
		Blocking:    1024
		Alpha mode:  matted to black
		Xoffset:     0
		Yoffset:     0
		Map ptr:     0
		Map name:

		----- Tile pointer table -----

		1 vertical tile, 1 horizontal tile
		Pointer		Length
		1024		0
	$ lfftoppm gaspra.lff > test.ppm
	$ xv test.ppm			    [ or whatever image utility]

    I didn't have any LFF files around, so I generated gaspra.lff from
mklffhdr and gaspra.raw (extracted from the original gaspra.ppm
image).

    doc/lff.ps is the document defining the Lucasfilm file format. Jim
Blinn & I both worked from it, and he could read files I generated (at
least, in 1985).

    man/ contains man pages for most of this stuff and some other code.

    No promises, etc. Hope this is useful.
