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 posi
tion 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 expect
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.

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.
