The GNU wdiff source package contains sources for a number of tools
besides wdiff itself.
These are considered experimental: they might work for you, but they
might just as well fail.
The following programs are considered experimental:
mdiff
wdiff2
unify
Building these applications can be configured at build time by passing --with-experimental to the configure script.
For this build, they have been disabled. Therefore their documentation has been omitted here as well. You can find the full documentation for all parts of GNU wdiff on the GNU wdiff homepage. If you feel you’d like to give them a try, you could compile this package from source yourself.
