NAME

     hlhclean - removes long path names at the start of all  his-
     torical line header entries

SYNOPSIS

     hlhclean [ -Nntap ] [ -Ootap ] [ -h ] [ -? ]

DESCRIPTION

     hlhclean is a (hopefully) temporary module built  to  fix  a
     problem  caused  during  the  introduction of the /apps/dist
     structure and the scripts used for firing up  USP  binaries.
     Because  the  scripts  actually exec the executable binaries
     invoking the full path name, the previous  library  routines
     used within USP would add that full name to the HLH entries.
     This has since been fixed in the hlh utility routines, but a
     total  re-linking  on  all architectures of the USP codes is
     required to totally eliminate the problem. This  program  is
     designed  to  "clean" datasets containing directory names in
     HLH entries until that time when it is no longer  necessary.
     This program would generally be run at the end of a process-
     ing flow prior to writing a dataset to disk. This  is  espe-
     cially  important  for dataset which are going to be plotted
     with the HLH annotation on a sidebar.

     hlhclean retrieve the data locations via command line  argu-
     ments. Currently, there are no processing options.

  Command line arguments
     -N ntap
          Enter the input data set name or file immediately after
          typing -N unless the input is from a pipe in which case
          the -N entry must be omitted.  This input  file  should
          include the complete path name if the file resides in a
          different directory.  Example -N/b/vsp/dummy tells  the
          program to look for file 'dummy' in directory '/b/vsp'.

     -O otap
          Enter the output data  set  name  or  file  immediately
          after typing -O.  This output file is not required when
          piping the output to another process.  The output  data
          set also requires the full path name (see above).

     -? | -h
          Enter either command line argument '-?' or '-h' to  get
          online  help.   The  program  terminates after the help
          screen is printed.

BUGS

     An option should probably added for removing long path names
     from dataset names in the HLH.
