 Mandelbrot checksum scripts for benchmarking Python 3.14's free-threaded interpreter
 
 **Background:**
+
 These scripts implement a CPU-intensive workload for calculating a checksum for a [Mandelbrot set](https://en.wikipedia.org/wiki/Mandelbrot_set).
 
 **Purpose:**
+
 These scripts were used to benchmark Python 3.14's new free-threaded interpreter against the classic GIL-enabled build for a CPU-bound workload.
 
 **Files:**
+
 Several versions of the benchmarking scripts were created to test out a sequential implementation, a multi-processing implementation, and a threaded implementation. A Bash driver script to automate testing and CPU cooldown cycles is also provided.
