       Functionality of this utility can be done from C with CPLAddFileInZip() or VSICopyFile().

       The sozip utility can be used to:

       • create a SOZip(Seek-OptimizedZIP) file

       • append files to an existing ZIP/SOZip file

       • list the contents of a ZIP/SOZip file

       • validate a SOZip file

       • convert an existing Zip file in a SOZip optimized one

       --help Show this help message and exit

       --help-general
              Gives a brief usage message for the generic GDAL commandline options and exit.

       --quiet
              Quiet mode. No progress message is emitted on the standard output.

       --verbose
              Verbose mode.

       -g--grow Grow an existing zip file with the content of the specified filename(s).  This is the default mode
              of the utility. This switch is here for compatibility with Info-ZIP zip utility

       --overwrite
              Overwrite the target zip file if it already exists.

       -l--list List  the files contained in the zip file in an output similar to Info-ZIP unzip utility, but with
              the addition of a column indicating whether each file is seek-optimized.

       --validate
              Validates a SOZip file. Baseline ZIP validation is done in a light way, limited to being  able  to
              browse  through  ZIP records with the InfoZIP-based ZIP reader used by GDAL. But validation of the
              SOZip-specific aspects is done in a more thorougful way.

       -r--recurse-paths
              Travels the directory structure of the specified directory/directories recursively.

       -j--junk-paths
              Store just the name of a saved file (junk the path), and do not store directory names. By default,
              sozip will store the full path (relative to the current directory).

       --optimize-from=<input.zip>
              Re-process   {input.zip}   to   generate   a   SOZip-optimized   .zip.   Options   --enable-sozip,
              --sozip-chunk-size and --sozip-min-file-size may be used in that mode.

       --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>
              Chunk size for a seek-optimized file. Defaults to 32768 bytes. The value is specified in bytes, or
              K and M suffix can be respectively used to specify a value in kilo-bytes or mega-bytes.

       --sozip-min-file-size=<value>
              Minimum  file  size  to  decide  if  a file should be seek-optimized, in --enable-sozip=auto mode.
              Defaults to 1 MB byte. The value is specified in bytes, or K, M or G suffix  can  be  respectively
              used to specify a value in kilo-bytes, mega-bytes or giga-bytes.

       --content-type=<value>
              Store  the  Content-Type for the file being added as a key-value pair in the extra field extension
              'KV' (0x564b) dedicated to storing key-value pair metadata

       <zip_filename>
              Filename of the zip file to create/append to/list.

       <filename>
              Filename of the file to add.

       Create a, potentially seek-optimized, ZIP file with the content of my.gpkg:

          sozip my.gpkg.zip my.gpkg

       Create a, potentially seek-optimized, ZIP file from the content of a source directory:

          sozip -r my.gpkg.zip source_dir/

       Create a, potentially seek-optimized, ZIP file from an existing ZIP file.

          sozip --convert-from=in.zip out.zip

       List the contents of a ZIP file and display which files are seek-optimized:

          sozip -l my.gpkg.zip

       Validates a SOZip file:

          sozip --validate my.gpkg.zip

       The GDAL_NUM_THREADS configuration option can be set to ALL_CPUS or a integer value to specify the number
       of threads to use for SOZip-compressed files. Defaults to ALL_CPUS.
