UCL-1.01-1 and UPX-1.20-1 are now installable from setup.exe

UCL by Markus F.X.J. Oberhumer:

- UCL is a portable lossless data compression library written in ANSI C.
- UCL implements a number of compression algorithms that achieve an
excellent compression ratio while allowing *very* fast decompression.
Decompression requires no additional memory.
- UCL is my OpenSource re-implementation of some NRV compression algorithms.
- As compared to LZO, the UCL algorithms achieve a better compression
ratio but decompression is a little bit slower. See below for some rough

UPX by Markus F.X.J. Oberhumer and László Molnár:

- UPX is a free, portable, extendable, high-performance executable
packer for several different executable formats. It achieves an
excellent compression ratio and offers very fast decompression. Your
executables suffer no memory overhead or other drawbacks.
- UPX is copyrighted software distributed under the terms of the GNU
General Public License, with special exceptions granting the free usage
for commercial programs as stated in the UPX License Agreement.
- UPX uses the NRV compression library for compression services. A
compatible but somewhat less efficient OpenSource implementation is
available through the UCL compression library.
- UPX aims to be Commercial Quality Freeware.
