CompilePal is a tool that you should use instead of VBCT + Pakrat + manual BSZip nowadays.
Featuring:
Easy install, runs from any directory and detects most Source mods files.
Customizable compile presets: compile for any map state in a few clicks.
Looks damn pretty.
Automatically packs your maps after compiling.
Repacks and builds cubemaps automatically as well.
Seriously, I don't get why there are any reasons to not use this.
