HLLib
HLLib is a LGPL open source programming library, which abstracts several Half-Life and Half-Life 2 package formats and provides a simple interface for all of them. HLLib works natively in both 
Windows and 
Linux.
HLLib is written in native C++ but exposes both a C and C++ interface which can be used in any C or C++ application (additional languages may also use the library with Win32 imports).
Created by Ryan "Nemesis" Gregg.

HLExtract
HLLib contains a example application called HLExtract. HLExtract is a GPL command-line utility written in C that can browse, extract, validate and defragment all supported packages. It provides a lean and mean shell-like interface for browsing as well as a command-line interface for automating tasks. HLExtract works natively in both Windows and Linux.
