Display the differences between OLD-TARGET and NEW-TARGET. PATHs, if * given, are relative to OLD-TARGET and NEW-TARGET and restrict the output * to differences for those paths. OLD-TARGET and NEW-TARGET may be working * copy paths or URL[@REV]. * * OLD-TARGET defaults to the path '.' and NEW-TARGET defaults to OLD-TARGET. * N defaults to BASE or, if OLD-TARGET is an URL, to HEAD. * M defaults to the current working version or, if NEW-TARGET is an URL, * to HEAD. * * '-r N' sets the revision of OLD-TGT to N, '-r N:M' also sets the * revision of NEW-TGT to M. * * 2. Shorthand for 'svn diff -r N:M --old=URL --new=URL'. * * 3. Shorthand for 'svn diff [-r N[:M]] --old=URL1 --new=URL2' * * Use just 'svn diff' to display local modifications in a working copy * * Conversion of the above usage examples to VersionControl_SVN_Diff: * * Example 1: * <code> * <?php * require_once 'VersionControl/SVN.php'; * * // Setup error handling -- always a good idea! * $svnstack = &PEAR_ErrorStack::singleton('VersionControl_SVN'); * * // Set up runtime options.
