			GifText
			-------

Program to print (text only) general information about GIF file

Usage:
------

Usage: GifText [-c] [-e] [-z] [-p] [-h] GifFile

  If no GifFile is given, GifText will try to read stdin for GIF file.
  As giftext can generate huge amount of data, ^C will kill it, but 'q' will
stop only the printing (of one of -e, -z, -p), while file integrity will still
be checked.


Memory required:

Options:
--------

1. [-c] : Dumps also color maps.
2. [-e] : Dumps also encoded bytes - the pixels after compressed using LZ
   algorithm and chained to form bytes. This is the form the data is saved
   in the GIF file. Dumps in hex - 2 digit per byte.
3. [-z] : Dumps also the LZ codes of the image. Dumps in hex - 3 digits per
   code (as we are limited to 12 bits).
4. [-p] : Dumps aslo the pixels of the image. Dumps in hex - 2 digit per
   pixel (<=byte).
5. [-h] : print one command line help, similar to Usage above.
