beam/examples/beamsh: basic implementation of the pipeline design, with static handlers for now.
...
In the pipeline design, several beam commands can be run concurrently,
with their respective inputs and outputs connected in such a way that
beam messages flow from the first to last. This is similar to the way
a unix shell executes commands in a pipeline: instead of STDIN and
STDOUT, each beam command has a "BEAMIN" and "BEAMOUT".
Since beam allows for richer communication than plain byte streams, beam
pipelines can express more powerful computation, while retaining the
fundamental elegance and ease of use of unix-style composition.

beam: more hooks for interactive debugging
...
This inserts low-level hooks for interactive step-by-step debugging.
Hooks are triggered by setting the *TEST* environment variable.
This is particularly useful for tracking down file descriptor leaks,
double-closing, or other issues which are difficult to debug with
the usual toolbox.
