DESCRIPTION

     ch_lab copies from one or more input label files to an output label file, optionally
     performing various operations along the way.

     The following option flags are recognized:

           -h    Print a summary of usage to standard output.
           -S frame spacing
                 frame spacing of output
           -start time
                 start time, in seconds, for label extraction
           -end time
                 end time, in seconds, for label extraction
           -ext file extension
                 filename extension to use for multiple output files
           -extract file
                 extract a single file from a list of files
           -extend time
                 extend track file by time seconds beyond label file
           -f sample frequency

           -lf sample frequency
                 sample frequency for labels
           -itype file type
                 type of input label file: esps htk ogi
           -key key file
                 key label file
           -lablist list
                 list of labels to be considered as blank
           -length time
                 length of track produced, in seconds
           -map map file
                 label mapping file
           -name feature name

           -class class
                 name of class defined in op file
           -o output file
                 output file name
           -otype file type
                 output file type: xmg, ascii, esps, htk
           -pad high | low
                 pad with high or low values
           -pos list
                 list of labels to be regarded as 'pos'
           -q timestep
                 quantize label timings to nearst value
           -range range
                 difference between high and low values
           -sed sed file
                 perform regex editing using sed file
           fl shift time delta
                 shift the times of the labels
