rot - the world's worst pager (1980)
I wrote this around 1980, it's the oldest code I have that still exists and works.
It's the world's worst pager
cc rot.c -O -o rot -ltermlib
cc rot.c -O -o rot -lcurses
Because most systems don't have a separate TERMCAP library any more.
This is still a Version 6 C program, and might even build on a PDP-11 in 1978 if you happen to have a time machine. This means there's a boatload of warnings due to the pre-ANSI function definitions. Deal with them. I will accept pull requests for this but they'll be tossed into a seprate branch because this silly thing is a historical artifact.
