This package consists of programs based on Donald Knuth's WEB System of 
Structured Documentation, which is the programming methodology used to 
develop the TeX document compiler, the METAFONT typeface compiler, and 
all of the support programs for both.

The package is composed of three parts:

       1) MWEB, a variation of the WEB system which has been adapted to
               the Modula-2 language (regular WEB uses Pascal as its 
               programming language)

       2) WEBMERGE, a program to merge multiple change files together (change 
               files are used to make implementation-dependent changes to an 
               implementation-independent base WEB file---the WEB processors 
               allow only one change file per WEB file)

       3) SCANTEX/SCANWEAVE, programs to strip out the parts of a WEB 
               listing which have not been modified by a change file.

       4) the LaTex sources for the slides used in session LT005 (Literate 
               Programming: The WEB System of Structured Documentation) at the
               DECUS Fall 1987 Symposium in Anaheim, with the sample program
               used in the session.


WEB itself is not included in this submission; it is normally bundled with
TeX and can be found elsewhere in the DECUS library.  TeX is required to use 
this package anyway, and WEB will come with it.


This directory structure contains:

[.webm]

     	Files pertaining to WEBMERGE.  Print the User's Guide (WEBMUSER.TEX), 
        which is in LaTeX form, for more information.

[.mweb]

	Files pertaining to MWEB, a Modula-2 version of the WEB system.  Print 
        the User's Guide (MWEBUSER.TEX), which is in LaTeX form, for more 
	information.

[.scan]

	Files pertaining to SCANTEX/SCANWEAVE, programs to scan TeX files
	output by WEAVE and remove sections which have not changed.  Print the 
        User's Guide (SCANUSER.TEX), which is in LaTeX form, for more 
        information.
     

[.lt005_87f_talk]

        LaTeX sources and sample program for session LT005 at Anaheim 1987.



All of the documentation for these programs is in LaTeX source form.  If you
don't have a running TeX/WEB system, the programs will be useless anyway.  If
you have TeX running, but not LaTeX, the DVI files are provided and can be 
sent directly to the TeX device driver for your output device.
