Example:

loadrt u32runner [count=N|names=name1[,name2...]]

runner.N.run bit in => run
runner.N.from u32 in => Number to start =>(just nice to have)
runner.N.to u32 in => Number to count to =>(if there is no "from" this can also be "THE" number)
runner.N.speed s32 in => count speed =>(must have - can also be an u32 if in ms)
runner.N.cycle bit in => repeat yes/no =>(must have)
runner.N.rev bit in => count backwards =>(just nice to have)
runner.N.warp bit in => one way or up and down =>(one way is need, up and down is nice to have)
runner.N.out u32 out => output =>(need of course)
