usage: compreffor [-h] [-v] [-c] [-d] [-n NROUNDS] [-m MAX_SUBRS] [--generate-cff] [--py]
                  [--chunk-ratio CHUNK_RATIO] [-p PROCESSES]
                  INPUT [OUTPUT]

FontTools Compreffor will take a CFF-flavored OpenType font and automatically detect repeated
routines and generate subroutines to minimize the disk space needed to represent a font.

positional arguments:
  INPUT                 path to the input font file
  OUTPUT                path to the compressed file (default: *.compressed.otf)

options:
  -h, --help            show this help message and exit
  -v, --verbose         print more messages to stdout; use it multiple times to increase the level
                        of verbosity
  -c, --check           verify that the outputted font is valid and functionally equivalent to the
                        input
  -d, --decompress      decompress source before compressing (necessary if there are subroutines
                        in the source)
  -n, --nrounds NROUNDS
                        the number of iterations to run the algorithm (default: 4)
  -m, --max-subrs MAX_SUBRS
                        limit to the number of subroutines per INDEX (default: 65533)
  --generate-cff        Also save binary CFF table data as {INPUT}.cff
  --py                  Use pure Python method, instead of C++ extension

options for pure Python method:
  --chunk-ratio CHUNK_RATIO
                        specify the percentage size of the job chunks used for parallel processing
                        (0 < float <= 1; default: 0.1)
  -p, --processes PROCESSES
                        specify number of concurrent processes to run. Use value 1 to perform
                        operation serially (default: 12)
