This release of the GIFKIT contains GIFLS, GIFSTRIP, and GIFCOLOR, three
utilities for the analysis and manipulation of GIF files which I wrote
originally because I needed them. Since then, I have polished them
sufficiently for release.
THESE PROGRAMS ARE NOT PUBLIC DOMAIN. THEY ARE SHAREWARE. You may use
them with no obligation for a week; thereafter, you should register with
me for a nominal fee ($5.00). The GIFKIT may be distributed freely so long
as it is not modified. There is no warranty on these programs. They
and any associated documentation are provided strictly as-is.
These programs are written in C. Hardware- and OS-dependent routines are
isolated in separate files. Hence, these programs are reasonably portable.

code for MS-DOS and UNIX systems is already available. In this case, the
user should be prepared to give me a copy of the new source once the port

In circumstances other than these, I would prefer to do any and all
modifications of the programs myself. If I'm going to be blamed for mistakes
in these programs, I'd like the mistakes to be mine. However, if you think
you have a good reason for wanting the source code, talk to me about it.
