UPX - "another" executables compression utility ...

Hi, Some time ago someone mentioned here some compression utility/app. My friend found some UPX. I don't remember if it is the tool which was already suggested to RT, or it is just another one ... but here is the link: 514KB Rebol/View exe --> 318KB new Rebol/View exe ... ... all you need is upx.exe (89KB) ... it can pack .dll and possibly other stuff ... nice! It's free ... source codes available ... multiplatform ... http://upx.sourceforge.net ... -pekr-
