SVN: Track merges

Is it possible in SVN 1.6 to track where a commit was merged. I'm especially interesting in UI based solution (Eclipse plugin will be great).

Thank you for all answered person (special thanks to derobert and Jim T). I write my own code using svnkit 1.2.x that do what I exactly need.

private static void showMergedRevision(String pFromUrl, String pToUrl) throws SVNException {
    List<String> folders= new ArrayList<String>();
    folders.add("Folder1");
    ...

    SVNRepositoryFactoryImpl.setup();

     String name="user";
     String password="password";

     ISVNOptions options = SVNWCUtil.createDefaultOptions( true );

     ISVNAuthenticationManager authManager = SVNWCUtil.createDefaultAuthenticationManager(name, password);

     SVNClientManager ourClientManager = SVNClientManager.newInstance( options , authManager );

     final Set<Long> mergedRevision = new HashSet<Long>();        
     for(String folder : folders){
         SVNURL svnFrom = SVNURL.parseURIDecoded(pFromUrl + "/" + folder);
         SVNURL svnTo = SVNURL.parseURIDecoded(pToUrl+ "/" + folder);
         ISVNLogEntryHandler mergedLogger = new ISVNLogEntryHandler() {
            public void handleLogEntry(SVNLogEntry pParamSVNLogEntry) throws SVNException {
                mergedRevision.add(pParamSVNLogEntry.getRevision());
            }
        };
        ourClientManager.getDiffClient().doGetLogMergedMergeInfo(svnTo, SVNRevision.HEAD, svnFrom, SVNRevision.HEAD, false, null, mergedLogger);
     }

     System.out.println(String.format("Tracking merges from [%s] to [%s].", pFromUrl, pToUrl));
     System.out.println("Comparing folders: " + folders);

     SVNURL svnUrlorg = SVNURL.parseURIDecoded(pFromUrl);
     ISVNLogEntryHandler histroyLogger= new ISVNLogEntryHandler() {
        public void handleLogEntry(SVNLogEntry pParamSVNLogEntry) throws SVNException {
            if (pParamSVNLogEntry.getRevision() < 0){
                // Sometimes got -1 null null null values. Skip them
                return;
            }
            final boolean merged = mergedRevision.contains(pParamSVNLogEntry.getRevision());
            System.out.println(String.format("%s %s: %s %s %s", merged ? "[+]": "[-]", 
                    pParamSVNLogEntry.getRevision(), 
                    pParamSVNLogEntry.getAuthor(), pParamSVNLogEntry.getDate(), 
                    pParamSVNLogEntry.getMessage()));
        }
    }; 
    ourClientManager.getLogClient().doLog(svnUrlorg, null, SVNRevision.HEAD, SVNRevision.create(0), SVNRevision.HEAD, true, false, false, -1, null, histroyLogger);
}

The output will be:

[-] 7210: boa 03.07.2009
[-] 7211: boa 03.07.2009
[+] 7215: boa 03.07.2009

[+] means merged revision, [-] - unmerged.
