A love letter to Source Engine and Valve Software.

What's changed

• waifu renamed to waf
• Hammer's INFDEV Linux support
• Source code got more lightweight (Removed VProf/Telemetry)

What to expect

• Code cleanup (X360, PS3, etc.) 😊
• Utilities port to Linux
• SDL3 upgrade
• Vulkan instead of OpenGL/DirectX
• Replacement of proprietary technology with open-source alternatives
• Hammer's full Linux support (don't expect it, though...)
