Today I've been using openport and hcommand to try and get perl to talk 
to Houdini. I'm hoping to make some kind of an interface to the pipeline 
here for Houdini.

To do so I need to source a hscript command that starts a shell (unix 
command), so the shell can run a perl script, which then runs hcommand 
on the original Houdini process.

Two problems:
1./ STDOUT from hcommand is ending up in Houdini's parent shell and not 

2./ Is it just me - or does this seem like a tenuous foundation for an 
important pipeline interface?
