  # Pip Package Guide
  This pip package branch builds upon updated directory structure for concise import paths. All the modules are now sub-module of main bark module, and are imported w.r.t it. C++ python bindings previously in python folder are now in python_wrapper folder under bark main directory and similarly components from module directory are also placed under bark directory. C++ python library is renamed `core.so` from `bark.so`.
