-dwdiff is a front-end for the 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.
