The program was written under LINUX with gcc (ANSI, K&R). Problems on other
architectures can arise with the byte order.

Usually the linux binary will be supplied.

To compile the program type:

	make

Copy the executeable 'pnmtoprt' to any place in your path.

On other systems than linux you have to change the compiler and the compiler
options in the Makefile. It is possible that you get problems with different
byte ordering. Please mail suggestions, I will take care of it in future
changes.
