00005 # This script is used to copy a root file of histograms,
00006 # together with its log files, in a destination directory.
00007 # Log files will be automatically compressed.
00008 #
00009 # Command-line options :
00010 #
00011 #   -f : force the copy, even if the destination file already exists.
00012 #   -r <name> : name of this set of histograms.
00013 #   -m <message> : specific comment about this set of histograms.
00014 #   -a <analyzers> : slash separated list of analyzers.
00015 #   -c <config> : slash separated list of cmsRun configurations.
00016 # 
00017 # Command-line arguments :
00018 #
00019 #   $1 : path of the ROOT file containing the histograms.
00020 #   $... : path of log files.
00021 #   $n : destination directory.
