This program is usable for debugging PM programs by inserting [f]printf statements. Use this program like this you-PM-program |& pmpipe or you-PM-program 2>&1 | pmpipe depending on your shell. (I suppose you already started pmprintf.exe - available on EWS). All the STDOUT/STDERR messages of your program appear on pmprintf console. ilya@math.ohio-state.edu (Ilya Zakharevich)
