RedHat 9 (Linux i386) - man page for dehtmldiff (redhat section 1)

DEHTMLDIFF(1)															     DEHTMLDIFF(1)

NAME
dehtmldiff - get usable diff from an HTML page
SYNOPSIS
dehtmldiff [file...] dehtmldiff {--help | --version}
DESCRIPTION
dehtmldiff creates usable diff files from HTML pages. This is useful in the scenario where a patch has been posted to a mailing list view- able via a web page. The corrected diff is sent to standard output. Note that you will probably need to use the -l option when applying the patch, in order to ignore any whitespace differences there may be.
OPTIONS
--help Display a short usage message. --version Display the version number of dehtmldiff.
LIMITATIONS
The way this command works is fairly primitive; it boils down to some simple text replacements, followed by an unwrapdiff pass. As a result, all of the limitations that apply to unwrapdiff also apply to dehtmldiff.
