Package kv3 reads binary KeyValues3 versions 4 and 5 and writes version 5, the format Source 2 compiled resources store their data in.

Package panorama compiles Panorama layouts and scripts into the resources the game loads, without Valve's resource compiler, and decompiles layouts back to XML.

Package resource reads and writes the container of a Source 2 compiled resource, such as a .vxml_c layout or a .vents_c entity lump: a header and a table of tagged blocks, each holding one part of the resource.

Package vpk reads and writes Valve archives (VPK), the packages Source 2 games mount their resources from.
