  Description: 'The StreamWeaver'  Graphical environment for shell commands amd pipes
        Usage:	The zip archive should unpack into a complete, ready-to-run,
				directory hierarchy.  See the README in the package for a
				walk-through. (The Weaver program itself is identical to that in
				the 'MusicWeaver' suite. You only need one copy.)

The StreamWeaver modules give you a 'visual analogue' of unix-style pipes,
using the Weaver diagram manager program.  The central 'PipeStream' module
will run any shell command line,  and you can set up any number of these in
a diagram, connected together with 'pipelines' that feed the output from one
module to the input of another.  Another module -- 'StreamView'  --provides
for input and output of editable text data in a window, and two others
-- 'ReadFile' and 'WriteFile' -- let you pass file data directly to and from
pipelines.  In addition to providing a basis for visual pipes, these modules
can be very convenient for quick access to, and manipulation of, input and
output data.

Building a 'diagram' in the Weaver is simply a matter of dragging the desired
elements into the Weaver's window, and then dragging connecting paths between
them.
