SlackBuildsOrg/misc/dwdiff

dwdiff is a diff program that operates at the word level instead of
the line level. It is different from wdiff in that it allows the user
to specify what should be considered whitespace, and in that it takes
an optional list of characters that should be considered delimiters.
Delimiters are single characters that are treated as if they are
words, even when there is no whitespace separating them from preceding
words or delimiters. dwdiff is mostly commandline compatible with
wdiff. Only the --autopager, --terminal and --avoid-wraps options are
not supported.

The default output from dwdiff is the new text, with the deleted and
inserted parts annotated with markers. Command line options are
available to change both what is printed, and the markers.

If you wish to have nl manpages and/or de, fr, nl, ru localization pass
'NLS="de fr nl ru"' (or whichever of them is wanted) to the SlackBuild.

If you wish to enable the handling of Unicode text, pass "UNICODE=yes"
to the SlackBuild script.
