* JimCreatePipeline --

* as described by the argv.
*
* Results:
* The return value is a count of the number of new processes
* created, or -1 if an error occurred while creating the pipeline.
* *pidArrayPtr is filled in with the address of a dynamically
* allocated array giving the ids of all of the processes. It
* is up to the caller to free this array when it isn't needed
* anymore. If inPipePtr is non-NULL, *inPipePtr is filled in
* with the file id for the input pipe for the pipeline (if any):
* the caller must eventually close this file. If outPipePtr
* isn't NULL, then *outPipePtr is filled in with the file id
* for the output pipe from the pipeline: the caller must close
* this file. If errFilePtr isn't NULL, then *errFilePtr is filled
* with a file id that may be used to read error output after the
* pipeline completes.
*
* Side effects:
* Processes and pipes are created.
