What is it?
This program generates an incremental patch from two patches against a
common source. For example, if you have applied a pre-patch to a
source tree, and wish to apply another pre-patch (which is against the
same original source tree), you can use interdiff to generate the
patch that you need to apply. You can also use this to review changes
between two pre-patches.
Where is it?
Interdiff currently only works for unified diff format patches.
A "No" uttered from deepest conviction is better and greater than a
"Yes" merely uttered to please, or what is worse, to avoid trouble.
