Project: Compression algorithms. Author: Arkadi Kagan <arkadi_kagan@hotmail.com>

The project presents main known looseless compression algorithms.
All algorithms are implemented in their simplest form.

The project was compiled on:
1. Microsoft Visual Studio 6.0
2. g++ (GCC) 3.3.1 (cygming special)
3. g++ (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
The code was done for Intel-compatible CPU.
For Big-Endian and other non-Intel architectures there is a need for some porting. I will try to avoid it from this project.

The project is compiled to command-line program "coder".
Use this program like this:
    coder [block_size] -{d|{e{a|h|7|8|w|c|f}}}
Where:

	block_size	- Size of sub block of data to encode
	<source>	- Source file name
	<target>	- Target file name

Options requered:

	e	- Encode file
	d	- Decode file

Encoding methods:

	a	- Arithmetic coding
	h	- Huffman coding
	7	- LZ77 coding
	8	- LZ78 coding
	w	- LZW coding
	r	- RLE coding

For example:
    If I want to compress source file by LZW and after
    that Arithmetic coding, I should only type:
        coder -ewa source_file target_file
    To decode it back to source:
        coder -d compressed_file target_file

I did an attempt to gather documentation on most importent Entropy Comression Methods.
This document among to my own text contain some links to other sources.
