This directory contains programs and documentation for reading and modifying
the header for CVL format picture files.

Compiling these programs requires two steps:
1) Go to the "lib" subdirectory and compile the functions into a library
module.  If  you have the "make" program, simply type:

make all

If you have no "make" program, then you need to do whatever is appropriate
for your system to compile the functions into a library named "libcvl.a".

2) Come back to this directory and compile the programs.  Once again, if
you have "make", just type:

make cmd

This will give you the following programs for manipulating CVL picture files.
For more information, see the "man" sections in this directory.

header - print the picture parameters and comments in a CVL picture header
edhead - edit a CVL picture file header using a screen editor
chghead - change parameters of a CVL picture file header
chcmnt - change the comments of a CVL picture file
crehead - create a CVL picture file header for pre-pending to raw data
normalize - fill out the comments field so that data falls on a block boundary
convert - change the long word byte order for compatability between machines
	with differing byte orders (e.g., VAX and SUN)
