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.

Several Linux distributions and BSD version are shipping dwdiff packages or build scripts/ports, for example Fedora Linux, FreeBSD and OpenBSD. For some Unix variants or derivatives, dwdiff packages are provided through external repositories:
- SPARC/Solaris 2.5-10 and x86/Solaris 8-10, provided by Steve Christensen on his sunfreeware.com site.
- Mac OS X, through MacPorts or Homebrew.
- Slackware Linux, through Slackbuilds.org and Slacky.eu.
- The OpenPKG project (a generic Unix/Linux packaging system).
If your distribution does not provide dwdiff packages, you can either build dwdiff from source, or you can try filing a feature request with the maintainers of your distribution.
