host2cpm \[-r\] \[-d 'dirpath\[filter\]'\] \[-cpm 'filepath'\] \[-f 'filter'\]
host2cpm -h
   Moves multiple files in a dir to/from the cpm disk.
      -r optional - reverse cpm->host, instead of default host->cpm
      -d optional - the directory pathname  of the host directory
         to be copied/updated.
         For host->cpm, if the path is a directory name, all the files in the
         directory will be copied. If the path includes a quoted glob pattern,
         only the selected files will be copied. Example '-d 'work/cpm/*.ASM'.
         Glob patterns must be quoted so that the shell does not expand them
         before passing the argument to the script.
         For (-r) reverse mode cpm->host just the directory path should be
         supplied, all files  from the cpm disk will be copied to the host
         directory unless the a filter is supplied ( see the -f option ).
         Defaults to the current dir.
      -cpm optional - the file of the cpm disk image. Default is the name of the 
         current dir with .dsk appended. For direction host->cpm if the file does
         not exist, a new empty disk file is created.
      -f optional - the CPM file glob pattern selects files to be copied.
         EX -f '*.ASM' - Must be quoted from the shell. 
      -h help - only display this message. "
