 As of version 2025.10.10, you don't need to worry about those problems anymore. The entrypoints to Pwndbg are the `pwndbg` and `pwndbg-lldb` commands as defined in the `[project.scripts]` section of the `pyproject.toml` file.

The method you use to package any python package will just work with Pwndbg without any workarounds.
