When typing the command info you get a long output with header as:

File: dir,      Node: Top       This is the top of the INFO tree

  This (the Directory node) gives a menu of major topics.
  Typing "q" exits, "?" lists all Info commands, "d" returns here,
  "h" gives a primer for first-timers,
  "mEmacs<Return>" visits the Emacs manual, etc.

  In Emacs, you can click mouse button 2 on a menu item or cross reference
  to select it.

So, from the heading I assume that using emacs as the default PAGER but when running the command

emacs

output shows:

The program 'emacs' can be found in the following packages:
 * emacs23
 * emacs23-nox
 * e3
 * emacs23-lucid
 * jove
Try: sudo apt-get install <selected package>

Then what is the pager of info pages? Is there is some bundled emacs or some like?!

Quoting the online info manual

There are two ways to use Info: from within Emacs or as a stand-alone reader that you can invoke from a shell using the command info.

I guess info has no external pager like man but info IS the pager.

/usr/bin/info (from package info) is a standalone info page viewer. It's not related to Emacs.

See info info for more about info.

The text you see if you start infO without an argument isn't created by info but the default info node (usually /usr/share/info/dir)

Quoted from http://www.gnu.org/software/texinfo/:

Texinfo is the official documentation format of the GNU project. It was invented by Richard Stallman and Bob Chassell many years ago, loosely based on Brian Reid's Scribe and other formatting languages of the time. It is used by many non-GNU projects as well. Texinfo uses a single source file to produce output in a number of formats, both online and printed (dvi, html, info, pdf, xml, etc.). This means that instead of writing different documents for online information and another for a printed manual, you need write only one document. And when the work is revised, you need revise only that one document. The Texinfo system is well-integrated with GNU Emacs.

To learn how to use texinfo read http://www.emacswiki.org/emacs/Texinfo

Reading some emacs WIKI:

This page is about Info mode (‘C-h i’), a major mode for reading hypertext manuals. In particular, the EmacsManual is available in Emacs as an Info manual, providing SelfDocumentation.

Quoted from http://www.emacswiki.org/emacs/EmacsManual:

Emacs comes with a comprehensive manual. Access it through Info, either with the info command in a shell window under GNU and Unix operating systems, or in Emacs, by typing ‘M-x info RET’ (that’s Meta- or ESC x, the word “info”, followed by the return key), or by typing ‘C-h i’ (that’s Control-h followed by i). Starting with Emacs 22, you can also read the manual with ‘C-h r’.

As a conclusion info pages use Textinfo documentation format but as said in the GNU Textinfo wiki The Texinfo system is well-integrated with GNU Emacs.
