DESCRIPTION ---------------- This module adds 'diff' functionality to the 'Revisions' tab, allowing users to nicely view all the changes between any two revisions of a node. Users may also preview their changes before saving a new node. TECHNICAL ------------------- - Diff compares the raw data, not the filtered output, making it easier to see changes to HTML entities, etc. - The diff engine itself is a GPL'ed php diff engine from phpwiki. API ----------------- - This module offers hook_diff() which modules may use to inject their changes into the presentation of the diff. For example, this is used by cck.inc, upload.inc, and taxonomy.inc in this package. TODO ----------------- - Consider using in core.
