<br>
I'm trying to start some processes and connect them using pipes with ABCL<br>
(like Unix shell pipes). I've reviewed the documentation but I haven't found<br>
anything. Are I missing something? If not, are there any plans of adding<br>
input, output and error parameters for run-program (like SBCL, CCL, etc.)?<br>
