## Summary:
The `setup' macro simplifies repetitive configuration patterns, by
providing context-sensitive local macros in `setup' bodies. These
macros can be mixed with regular elisp code without any issues,
allowing for flexible and terse configurations. The list of local
macros can be extended by the user via `setup-define'. A list of
currently known local macros are documented in the docstring for `setup'.
