# Stuck on a desert island with no internet, unable to load your meticulously categorized DevonThink database? 
# This could be come in handy!

# This code should probably be considered in the public domain since it is basically just vibe coded with a load of prompts,

# Lovingly vibe coded 100% in ChatGPT.

Building tgemit on OSX using SDL2

• Checkout the relevant branch (currently pbfix_mango)
• Make sure you have xcode, dev tools, and metal tools installed (i.e. xcodebuild -downloadComponent MetalToolchain)

Currently only dawn is known to work with this setup, so you need to build and install it somewhere. A script in lib can do this:

./build_dawn.sh getdeps ~/dawnbuild
./build_dawn.sh build ~/dawnbuild Release
