"""
Provide a session hook after the workspace has been built.
This runs after the workspace has been loaded with ``tmuxp load``. It
augments instead of replaces the ``before_script`` section of the
workspace data.
This hook provides access to the LibTmux.session object for any
behavior that would be used in the ``before_script`` section of the
workspace file that needs access directly to the session object.
This runs after the workspace has been loaded with ``tmuxp load``.
The hook augments, rather than replaces, the ``before_script`` section
of the workspace. While it is possible to do all of the
``before_script`` workspace in this function, if a shell script
is currently being used for the workspace, it would be cleaner to
continue using the script in the ``before_section``.
If changes to the session need to be made prior to
anything being built, please use ``before_workspace_builder`` instead.
Parameters
----------
session : :class:`libtmux.Session`
session to hook into
