 ## I want to use this!
 Download the DLL and .dm file from [Releases](https://github.com/MCHSL/extools/releases). Place the DLL next to your DMB and plop the .dm somewhere where you can easily tick it. Afterwards, add `extools_initialize()` to `world/New()` or equivalent. To load modules, call `<module>_initialize()`, for example `tffi_initialize()`. Module initialization functions must be called after `extools_initialize()`!
