Yes, but what's missing from all of these places is the overview (or
an example) of how would one go about running a pipeline of processes
using these functions, and a guided walk through the orchestrated
operation of these functions during such a pipeline, which would
explain the importance of each one in the process.  The pieces are
there, but the glue is missing, and since there are so many pieces and
tiny details, one can easily get lost in them.
