; kpack = Kolibri Packer
; Kolibri version
; Written by diamond in 2006, 2007 specially for KolibriOS
;
; Disassemled and corrected in 2010 specially for FASM
;            by Marat Zakiyanov aka Mario79, aka Mario
;
; Uses LZMA compression library by Igor Pavlov
; (for more information on LZMA and 7-Zip visit http://www.7-zip.org)
; (plain-C packer and ASM unpacker are ported by diamond)
