I. INTRODUCTION TO PKLITE
─────────────────────────────────────────────────────────
This section contains an introduction to the PKLITE data
compression software.
1. PKLITE OVERVIEW
─────────────────────────────────────────────────────────
PKLITE is an easy to use file compression program. It increases
your valuable disk space by compressing executable files (with
.EXE and .COM extensions). PKLITE will compress these executable
files so they will require much less disk space yet will still
run normally.
PKLITE compresses your files much like PKZIP, but it adds a small
amount of extraction code at the beginning of the executable
file. When you run an application that has been compressed with
PKLITE, the program will automatically be expanded into memory
and run. The compressing process does not change the operation
of the program at all, it merely reduces the disk space required
to store it. No additional memory is needed to run most programs
compressed with PKLITE.
PKLITE also has the ability to expand your files back to their
original size.

2. SYSTEM REQUIREMENTS
────────────────────────────────────────────────────────
PKLITE will run on any IBM PC or compatible with DOS 2.0 or
higher. Running a program that has been compressed with PKLITE
requires a maximum of 4K extra memory overhead to expand the
application in memory. Memory available to the application
remains the same as before it was compressed.
