Class Description

                                                                      
 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.
TFileMerger()
 Create file merger object.
~TFileMerger()
 Cleanup.
void PrintProgress(Long64_t bytesread, Long64_t size)
 Print file copy progress.
Bool_t Cp(const char *src, const char *dst, Bool_t progressbar, UInt_t buffersize)
 Allows to copy file from src to dst URL.
void Reset()
 Reset merger file list.
Bool_t AddFile(const char *url)
 Add file to file merger.
Bool_t OutputFile(const char *outputfile)
 Open merger output file.
void PrintFiles(Option_t *options)
 Print list of files being merged.
Bool_t Merge()
 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.
Bool_t MergeRecursive(TDirectory *target, TList *sourcelist)
 Recursively merge objects in the ROOT files.
TFileMerger()
const char * GetOutputFileName()
{ return fOutputFilename; }
Bool_t SetCWD(const char * /*path*/)
{ MayNotUse("SetCWD"); return kFALSE; }
const char * GetCWD()
{ MayNotUse("GetCWD"); return 0; }
