+-- Stress test for Premake. Creates a large (tunable, see local variables
+-- at start of file) number of projects, files, and configurations. Then
+-- generates them all while profiling the result.
+--
+-- Run it like normal, i.e. `premake5 --file=test_stress.lua gmake`. The 
+-- profile results will be placed at `build/profile.txt`.
