Generate a seek-optimized ZIP (SOZip) file.

Positional arguments:
  <zip_filename>                                               ZIP filename.
  <input_files>                                                Filename of the file to add. [nargs: 0 or more]

Optional arguments:
  -h, --help                                                   Shows short help message and exits.
  --long-usage                                                 Shows long help message and exits.
  --help-general                                               Report detailed help on general options.
  -r, --recurse-paths                                          Travels the directory structure of the specified directories recursively.
  -g, --grow                                                   Grow an existing zip file with the content of the specified filename(s). Default mode.
  --overwrite                                                  Overwrite the target zip file if it already exists.
  -l, --list                                                   List the files contained in the zip file.
  --validate                                                   Validates a ZIP/SOZip file.
  --optimize-from <input.zip>                                  Re-process {input.zip} to generate a SOZip-optimized .zip

Advanced options (detailed usage):
  --quiet                                                      Quiet mode. No progress message is emitted on the standard output.
  --verbose                                                    Verbose mode.
  -j, --junk-paths                                             Store just the name of a saved file (junk the path), and do not store directory names.
  --enable-sozip auto|yes|no                                   In auto mode, a file is seek-optimized only if its size is above the value of
                                                               --sozip-chunk-size. In yes mode, all input files will be seek-optimized.
                                                               In no mode, no input files will be seek-optimized.
  --sozip-chunk-size <value in bytes or with K/M suffix>       Chunk size for a seek-optimized file. Defaults to 32768 bytes.
  --sozip-min-file-size <value in bytes or with K/M/G suffix>  Minimum file size to decide if a file should be seek-optimized. Defaults to 1 MB byte.
  --content-type <string>                                      Store the Content-Type for the file being added.
