# Handmade Math 2.0 Update Tool

Due to the large number of breaking naming changes in Handmade Math 2, we provide a small Python script to update your programs automatically. It can run on individual files or on all files in a directory (recursively).

**Warning!** This tool is not very smart! Please ensure that your work is committed and backed up, in case you have to revert this tool's changes.
