INTRODUCTION
============

UPX is an advanced executable file compressor. UPX will typically
reduce the file size of programs and DLLs by around 50%-70%, thus
reducing disk space, network load times, download times and
other distribution and storage costs.

Programs and libraries compressed by UPX are completely self-contained
and run exactly as before, with no runtime or memory penalty.

UPX supports a number of different executable formats, including
Win95/98/NT programs and DLLs, and DOS programs.

UPX may be distributed and used freely, even with commercial applications.
See the UPX License Agreement for details.

UPX is rated number one in the well known Archive Comparison Test. Visit
http://web.act.by.net/~act/act-exepack.html


SHORT DOCUMENTATION
===================

`upx program.exe' will compress a program or DLL. For best compression
results try `upx --best program.exe'.

Please see the file UPX.DOC for the full documentation. The files
NEWS and BUGS also contain various tidbits of information.


DISCLAIMER
==========

This is a beta-test release, so DO NOT USE THIS VERSION EXCEPT FOR
TESTING. Only compress backups of your executables. Be prepared
for crashes and other nasty surprises.

This version is not compatible with any previous or future release !

UPX comes with ABSOLUTELY NO WARRANTY; for details see the file LICENSE.

Having said that, we think that UPX is quite stable now. Indeed we
have compressed lots of files without any problems. Also, the
current version has undergone several months of beta testing -
actually it's 15 months since our first public beta.

Please report all problems or suggestions to the authors. Thanks.


THE FUTURE
==========

  - We'll implement unpacking of win32/pe and rtm32/pe programs in
    UPX 0.90.

  - We'd really love to support handheld systems like the PalmPilot because
    compression makes a lot of sense here. And - because of the atari/tos
    format - we already have a working decompressor in 68000 assembly.
    Unfortunately we know next to nothing about the operating system
    architecture of such handhelds, so we need some information from
    an expert. Please contact us if you think you can help.

  - The Linux approach could probably get ported to a lot of other Unix
    variants, at least for other i386 architectures it shouldn't be too
    much work. If someone sends me a fresh hard disk and an official
    FreeBSD/OpenBSD/NetBSD/Solaris/BeOS... CD I might take a look at it ;-)

  - There are currently no plans to support the OS/2 LX and 16-bit
    Windows 3.x executable formats.

  - We will *NOT* add any sort of protection and/or encryption.
    This only gives people a false feeling of security because
    by definition all protectors/compressors can be broken.
    And don't trust any advertisment of authors of other executable
    compressors about this topic - just do a websearch on something
    like "procdump"...

  - Fix all remaining bugs - keep your reports coming ;-)
