Info: An Introduction
*********************
Info is a program for reading documentation, which you are using now.
To learn how to use Info, type the command `h'. It brings you to a
programmed instruction sequence.
To learn advanced Info commands, type `n' twice. This brings you to
`Info for Experts', skipping over the . `Getting Started' chapter.

This first part of the Info manual describes how to get around inside
of Info. The second part of the manual describes various advanced Info
commands, and how to write an Info as distinct from a Texinfo file.
The third part is about how to generate Info files from Texinfo files.

Starting Info on a Small Screen
===============================
Since your terminal has an unusually small number of lines on its
screen, it is necessary to give you special advice at the beginning.
If you see the text `--All----' at near the bottom right corner of
the screen, it means the entire text you are looking at fits on the
screen. If you see `--Top----' instead, it means that there is more
text below that does not fit. To move forward through the text and see
another screen full, press the Space bar, SPC. To move back up, press
the key labeled `Rubout' or `Delete' or DEL.
Here are 40 lines of junk, so you can try SPC and DEL and see what
they do. At the end are instructions of what you should do next.

If you have managed to get here, go back to the beginning with DEL, and
come back here again, then you understand SPC and DEL. So now type an
`n'--just one character; do not type the quotes and do not type the
Return key, RET, afterward--to get to the normal start of the course.

How to use Info
===============
You are talking to the program Info, for reading documentation.
Right now you are looking at one "Node" of Information. A node
contains text describing a specific topic at a specific level of
detail. This node's topic is "how to use Info".
The top line of a node is its "header". This node's header (look at
it now) says that it is the node named `Help' in the file `info'. It
says that the `Next' node after this one is the node called `Help-P'.
An advanced Info command lets you go to any node whose name you know.
Besides a `Next', a node can have a `Previous' or an `Up'. This
node has a `Previous' but no `Up', as you can see.
Now it is time to move on to the `Next' node, named `Help-P'.
>> Type `n' to move there. Type just one character; do not type
the quotes and do not type a RET afterward.
`>>' in the margin means it is really time to try a command.
File: info.info, Node: Help-P, Next: Help-^L, Prev: Help, Up: Getting Started
Returning to the Previous node
==============================
This node is called `Help-P'. The `Previous' node, as you see, is
`Help', which is the one you just came from using the `n' command.
Another `n' command now would take you to the next node, `Help-^L'.
>> But do not do that yet. First, try the `p' command, which takes
you to the `Previous' node. When you get there, you can do an `n'
again to return here.
This all probably seems insultingly simple so far, but *do not* be
led into skimming. Things will get more complicated soon. Also, do
not try a new command until you are told it is time to. Otherwise, you
may make Info skip past an important warning that was coming up.
>> Now do an `n' to get to the node `Help-^L' and learn more.
File: info.info, Node: Help-^L, Next: Help-M, Prev: Help-P, Up: Getting Started
The Space, Rubout, B and ^L commands.
=====================================
This node's header tells you that you are now at node `Help-^L', and
that `p' would get you back to `Help-P'. The node's title is
underlined; it says what the node is about (most nodes have titles).
This is a big node and it does not all fit on your display screen.
You can tell that there is more that is not visible because you can see
the string `--Top-----' rather than `--All----' near the bottom right
corner of the screen.
The SPC, DEL and `b' commands exist to allow you to "move around" in
a node that does not all fit on the screen at once. SPC moves forward,
to show what was below the bottom of the screen. DEL moves backward,
to show what was above the top of the screen (there is not anything
above the top until you have typed some spaces).
>> Now try typing a SPC (afterward, type a DEL to return here).
When you type the SPC, the two lines that were at the bottom of the
screen appear at the top, followed by more lines. DEL takes the two
lines from the top and moves them to the bottom, *usually*, but if
there are not a full screen's worth of lines above them they may not
make it all the way to the bottom.
If you type a SPC when there is no more to see, it rings the bell
and otherwise does nothing. The same goes for a DEL when the header of
the node is visible.
If your screen is ever garbaged, you can tell Info to print it out
again by typing `C-l' (`Control-L', that is--hold down "Control" and
type an L or `l').
>> Type `C-l' now.
To move back to the beginning of the node you are on, you can type a
lot of DELs. You can also type simply `b' for beginning.
>> Try that now. (I have put in enough verbiage to make sure you are
not on the first screenful now). Then come back, typing SPC
several times.
You have just learned a considerable number of commands. If you
want to use one but have trouble remembering which, you should type a ?
which prints out a brief list of commands. When you are finished
looking at the list, make it go away by typing a SPC.
>> Type a ? now. After it finishes, type a SPC.
(If you are using the standalone Info reader, type `l' to return
here.)
From now on, you will encounter large nodes without warning, and
will be expected to know how to use SPC and DE
