+Builtin
+=======
+
+Builtin functions and builtin syntaxes are represented with
+`lsp_builtin_entry_t` structures. Each entry is defined with unique
+name and function pointer:
+
+.. code-block:: c
+
+    typedef lsp_status_t (*lsp_builtin_cb_t)(lsp_env_t *e, lsp_addr_t ctx, lsp_addr_t args);
+
+Associated function pointer is called during function/syntax application
+(described in following chapters).
