Upx: executable packer
1.24
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 because of in-place decompression.
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.
This port of UPX uses the UCL compression library, which is a somewhat less efficient OpenSource implementation compatible with the NRV compression library for compression services <http://www.oberhumer.com/products/nrv>;.
