rem Tests for the gif_lib utilities.
rem Usage:
rem	testgif [gif_dir] [display_prgm]
rem
rem   This test assumes the gif_lib utilities are available from one of the
rem path directorys, and that DIR is set (directly or through command line)
rem to the directory holf these gif files:
rem 1. SOLID2.GIF
rem 2. CHERYL.GIF
rem 3. PORSCHE.GIF
rem   In addition, set DISPLAY ( directly or through command line) to the
rem program to display gif files in our system.
rem   As this batch file intensively uses pipes which on msdos are saved as
rem files on CURRENT disk, it is going to be a good idea to execute this batch
rem from a ram disk.
