  46 Add entries to .gitignore . Default action is to add to .gitignore in
  47 the local directory, this can be overriden with -t/--top to update the
  48 .gitignore in the top directory of the repository. Wildcards can be
  49 used, and if any of the arguments is a directory, a trailing slash will
  50 be added if it doesn't exist already.
  51
  52 Usage: $progname [options] file [files [...]]
  53
  54 Options:
  55
  56   -h, --help
  57     Show this help.
  58   -q, --quiet
  59     Be more quiet. Can be repeated to increase silence.
  60   -s, --subdirs
  61     Don't prefix the new entries in .gitignore with '/', let the ignore
  62     rule work in all subdirectories too. For example, *.o files should
  63     generally be ignored all over the place, but without this option
  64     only *.o files in the directory where .gitignore is located are
  65     ignored.
  66   -t, --top
  67     Update the .gitignore in the top directory of the repository instead
  68     of .gitignore in the current directory.
  69   -v, --verbose
  70     Increase level of verbosity. Can be repeated.
  71   --version
  72     Print version information.
