Usage: jbig2dec [options] <file.jbig2>
   or  jbig2dec [options] <global_stream> <page_stream>

  When invoked with a single file, it attempts to parse it as
  a normal jbig2 file. Invoked with two files, it treats the
  first as the global segments, and the second as the segment
  stream for a particular page. This is useful for examining
  embedded streams.

  available options:
    -h --help       this usage summary
    -q --quiet      suppress diagnostic output
    -v --verbose    set the verbosity level
    -d --dump       print the structure of the jbig2 file
                    rather than explicitly decoding
    -V --version    program name and version information
    -m --hash       print a hash of the decoded document
    -e --embedded   expect embedded bit stream without file header
    -M <limit>      memory limit expressed in bytes
    -o <file>
    --output <file> send decoded output to <file>
                    Defaults to the the input with a different
                    extension. Pass '-' for stdout.
    -t <type>
    --format <type> force a particular output file format
