-Python-BPF is an LLVM IR generator for eBPF programs written in Python. It uses [llvmlite](https://github.com/numba/llvmlite) to generate LLVM IR and then compiles to LLVM object files. These object files can be loaded into the kernel for execution. Unlike BCC, Python-BPF performs compilation without relying on its infrastructure.
