1) Printing documentation:

Documentation is in the PostScript file doc.ps. It is about 2 pages
long.

2) Making the program.

The makefile should be setup for most UNIX systems as is.  Simply type
"make" in the source code directory.  If an X library is required,
specifiy that with a -L(library path).

3) Testing the program.

A small set of three files of 128x128 Y 64x128 U,V is in 
blkint.jpg.1, blkint.jpg.2, blkint.jpg.3.  To display them,
type 

cv -iw 128 -ih 128 -SF blkint.jpg

(For an image sequence, e.g. from the MPEG or P64 programs, you must
press a key in the window to run.)

There are also two additional programs: 

cyuv2ppm and ppm2cyuv which convert between component YUV files and
PPM files.  For more information see the man pages cyuv2ppm.1 and
ppm2cyuv.1.
