 TFileMerger                                                          
                                                                      
 This class provides file copy and merging services.                  
                                                                      
 It can be used to copy files (not only ROOT files), using TFile or   
 any of its remote file access plugins. It is therefore usefull in    
 a Grid environment where the files might be accessable via Castor,   
 rfio, dcap, etc.                                                     
 The merging interface allows files containing histograms and trees   
 to be merged, like the standalone hadd program.                      
                                                                      

 Create file merger object.

 Cleanup.

 Print file copy progress.

 Allows to copy file from src to dst URL.

 Reset merger file list.

 Add file to file merger.

 Open merger output file.

 Print list of files being merged.

 Merge the files. If no output file was specified it will write into
 the file "FileMerger.root" in the working directory. Returns true
 on success, false in case of error.

 Recursively merge objects in the ROOT files.
