LZRW HEADER FILES
=================
Author : Ross Williams.
Date : 25-Jun-1991.
1. This file contains two header files used by the LZRW series data
compression algorithms:
compress.h - The header file for the algorithms.
port.h - Contains portability definitions.
2. This code is public domain.
3. port.h is included only as an example. Please ensure that your
own definitions for these macros are correct.
UPDATED
=======
Author : Matt Slot, Ambrosia Software.
Date : 18-Jan-2007.
Added dst_max field, routine now returns -1 instead of writing past buffer.
This change is also public domain.

/* Normally in C programming, for each .H file, there is a corresponding .C */

/* Here, there are many .C files corresponding to this header file. */
/* Each comforming implementation file contains a single function */
/* called 'compress' that implements a single data compression */

/* DEFINITION OF FUNCTION COMPRESS */
/* =============================== */
/* */
/* Summary of Function Compress */
/* ---------------------------- */
/* The action that 'compress' takes depends on its first argument called */
/* 'action'. The function provides three actions: */
/* */
/* - Return information about the algorithm. */
/* - Compress a block of memory. */
/* - Decompress a block of memory. */
/* */
/* Parameters */
/* ---------- */
/* See the formal C definition later for a description of the parameters. */
/* */
/* Constants */
/* --------- */
/* COMPRESS_OVERRUN: The constant COMPRESS_OVERRUN defines by how many bytes */
/* an algorithm is allowed to expand a block during a compression op
