docify is a script to add docstrings to Python type stubs using reflection.

Features:
- Uses LibCST to parse and modify the stub file
- Dynamically imports the actual module to get the runtime docstring
- Handles most sys.version and sys.platform conditional blocks, will only add
  docstrings to the correct branch
- Able to modify files in-place with -i or --in-place
- Won't overwrite existing docstrings
- With -b or --builtins-only, will only add docstrings for modules found in
  sys.builtin_module_names (stdlib modules written in C).
- With --if-needed, will only add docstrings if the object's (Python) source
  code is unavailable. Useful for language servers like basedpyright that are
  able to extract docstrings from source code.
