New tutorial for review: "libelf by Example"

[Joseph Koshy]

Howdy list,

A tutorial introduction to the ELF(3)/GELF(3) API set is
available for review at the following URL:

  "libelf by Example"
  http://people.freebsd.org/~jkoshy/download/libelf/article.html

The intent is to add this tutorial to our documentation
collection.

Features:
- Covers the basics of the ELF format and ELF data
  structures.
- Contains an introduction to the ELF(3)/GELF(3) API set.
- Has 6 annotated programs showing the use of the
  API set:
  - Getting started with the elf(3) library.
  - Reading ELF data structures in an ELF object.
  - Creating new ELF objects.
  - Iterating through an ar(1) archive.
- 12 figures.

I would greatly appreciate review comments from people
with ELF expertise.
