List information about the repository in DIRECTORY. If no directory is
specified, the current directory is used. If multiple directories are
given, information will be fetched from the last directory specified.

Mandatory arguments to long options are mandatory for short options too.
Boolean arguments can only be given to long options.
  -f, --file-types=EXTENSIONS    a comma separated list of file extensions to
                                   include when computing statistics. The
                                   default extensions used are:
                                   {1}
  -F, --format=FORMAT            define in which format output should be

                                   the available formats are:

                                   projects; this is the same as supplying the

  -H, --hard[=BOOL]              track rows and look for duplicates harder;
                                   this can be quite slow with big repositories
  -l, --list-file-types[=BOOL]   list all the file extensions available in the

  -L, --localize-output[=BOOL]   localize the generated output to the selected
                                   system language if a translation is

  -m  --metrics[=BOOL]           include checks for certain metrics during the
                                   analysis of commits
  -r  --responsibilities[=BOOL]  show which files the different authors seem
                                   most responsible for
      --since=DATE               only show statistics for commits more recent

  -T, --timeline[=BOOL]          show commit timeline, including author names
      --until=DATE               only show statistics for commits older than a
                                   specific date
  -w, --weeks[=BOOL]             show all statistical information in weeks
                                   instead of in months
  -x, --exclude=PATTERN          an exclusion pattern describing the file
                                   paths, author names or author emails that
                                   should be excluded from the statistics; can
                                   be specified multiple times
  -h, --help                     display this help and exit
      --version                  output version information and exit
