deweb(1)		    General Commands Manual		      deweb(1)

NAME
       deweb - strips away C & CWEB commands from CWEB sources

SYNOPSIS
       deweb [ file1 file2 ...	]

DESCRIPTION
       deweb  filters away all C & CWEB	commands from a	CWEB source code. This
       leaves only the LaTeX code. This	stripped code, in turn,	 may  then  be
       passed to a suitable syntax checker for LaTeX, like ChkTeX and lacheck,
       or spell-checkers like ispell.

       The chkweb tool,	included in the	ChkTeX distribution will do just this;
       writing similar scripts should be trivial.

       When  deweb  strips  away the C code from your CWEB source, it tries to
       preserve	line breaks.  This means that the error	 reports   from	 _your
       favorite	 tool_	will  be  correct  regarding  to line numbers. In most
       cases, the column position will also  be	 correct.  This	 significantly
       simplifies  finding  the	errors in the LaTeX source (in contrast	to the
       output from cweave, which output	is truly difficult to figure  anything
       out from).

       deweb  accepts  a list of filenames on the argument line, and will send
       its output to stdout.  If no filenames are given,  it  will  read  from
       stdin, acting as	a filter. No options are currently accepted.

       Macho  users may	try to pipe the	output from deweb directly into	LaTeX,
       theoretically, this should work.	This would ease	the debugging  of  the
       LaTeX  code  significantly, as when LaTeX complains about wrong syntax,
       you'll be able to find the erroneous line much more easily.  Don't  ex-
       pect that the output looks very much like the final one,	though.

       deweb  should  now understand all correct CWEB opcodes. If it complains
       about not understanding a correct opcode, please	inform the author.

SEE ALSO

BUGS
       Doesn't even compile under Perl versions	before perl v5.	Unfortunately,
       this  means  that  we can't even	tell the user why we failed; Perl will
       just complain about not being able to compile the regexps.

       The program will	try to swallow the whole input file at	once,  instead
       of processing it	on a line-by-line basis.
