       Author:	Pete Goodeve (pete@jwgibbs.cchem.berkeley.edu)
      Release:	1.3 -- 17 May 1999
Compatibility:	BeOS release 4 and later PPC and x86
     Location:  contrib/util
  Description:	'The StreamWeaver'  Graphical environment for shell commands and pipes
        Notes:	Release 1.3 adds a regular-expression text scanning
		module 'Match' to the set from 1.2.  This understands
		'grep' like expressions, but is also UTF8-aware,
		matches across multiple lines, and lets you reformat
		the resulting match output.

        Usage:	The zip archive should unpack into a complete, ready-to-run,
		directory hierarchy.  (Choose the correct version -- ppc or x96
		-- for your system)  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.
		If you have the MusicWeaver already installed, unpack
		the StreamWeaver from the parent directory of that, so that
		the components get placed in the same Weaver folder.)


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.

The new 'Match' module lets you do things like extract all the link tags
from an HTML document, or watch a continuous text stream for particular
sequences.

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.

Release 1.1 was the first to run on x86 systems as well as PPC. It added
a SerialPort and a path Switcher module.  Release 1.2 made modest
improvements to StreamView, ReadFile, and WriteFile, but was otherwise
unchanged.  This 1.3 release adds the Match module.
