Using KDiff3 as a KPart

+KDiff3 is a KPart. Currently it implements the KParts::ReadOnlyPart-interface. +

+It's main use is as difference-viewer in KDevelop. KDevelop always starts the +internal difference viewer first. To invoke KDiff3 press the right mouse button +on the difference viewer window and select "Show in KDiff3Part" from the contextmenu. +

+KDiff3 normally requires two complete files as input. When used as part KDiff3 +will assume that the inputfile is a patch-file in the unified format. KDiff3 +then retrieves the original filenames from the patch-file. At least one of +the two files must be available. KDiff3 will then invoke patch to +recreate the second file. +

+In Konqueror you can select a patch-file and select "Preview in"-"KDiff3Part" from +the contextmenu. Be aware that this won't work if none of the original files are +available, and it is not reliable if the original file(s) have changed since the +patch-file was generated. +

+When run as a part KDiff3 only provides the a two-file-diff, a very small toolbar +and menu. Merging or directory-comparison are not supported then. +
