info -h ...
$ info -h
Usage: info [OPTION]... [MENU-ITEM...]

Read documentation in Info format.

Frequently-used options:
  -a, --all                    use all matching manuals
  -k, --apropos=STRING         look up STRING in all indices of all manuals
  -d, --directory=DIR          add DIR to INFOPATH
  -f, --file=MANUAL            specify Info manual to visit
  -h, --help                   display this help and exit
      --index-search=STRING    go to node pointed by index entry STRING
  -n, --node=NODENAME          specify nodes in first visited Info file
  -o, --output=FILE            output selected nodes to FILE
  -O, --show-options, --usage  go to command-line options node
      --subnodes               recursively output menu items
  -v, --variable VAR=VALUE     assign VALUE to Info variable VAR
      --version                display version information and exit
  -w, --where, --location      print physical location of Info file

The first non-option argument, if present, is the menu entry to start from;
it is searched for in all 'dir' files along INFOPATH.
If it is not present, info merges all 'dir' files and shows the result.
Any remaining arguments are treated as the names of menu
items relative to the initial node visited.

For a summary of key bindings, type H within Info.
