Usage: info [OPTION]... [MENU-ITEM...]
Read documentation in Info format.

-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.
--dribble=FILE remember user keystrokes in FILENAME.
-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.
-R, --raw-escapes output "raw" ANSI escapes (default).
--no-raw-escapes output escapes as literal text.
--restore=FILE read initial keystrokes from FILE.
-O, --show-options, --usage go to command-line options node.
--strict-node-location (for debugging) use Info file pointers as-is.

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.
Examples:
info show top-level dir menu
info info show the general manual for Info readers
info info-stnd show the manual specific to this Info program
info emacs start at emacs node from top-level dir
