 The file [`examples/juliac/juliac_pid.jl`](https://github.com/JuliaControl/DiscretePIDs.jl/blob/main/examples/juliac/juliac_pid.jl) contains a JuliaC-compatible interface that can be compiled into a C-callable shared library using JuliaC. To compile the file, run the following from the [`examples/juliac`](https://github.com/JuliaControl/DiscretePIDs.jl/tree/main/examples/juliac) folder:
 ```bash
