Unix specific instructions:

1. Download and transfer the perl file pstogif into your public_html directory on calclab1.math.tamu.edu, and rename it pstogif.pl
2. Make sure it is executable (chmod 755 pstogif.pl)
3. Download and transfer the binary file gifmerge into your public_html directory on calclabl, make sure it is executable
4. To run the programs, type ./pstogif and ./gifmerge (The ./ before the program tells unix to run the program in the current directory).
5. There is help available to typing "./pstogif -h" (without quotes) and "./gifmerge -h" (without quotes)
