-(defmacro ztree-defrecord (record-name record-fields)
-  "Create a record (structure) and getters/setters.
-
-Record is the following set of functions:
- - Record constructor with name \"RECORD-NAME\"-create and list of
-arguments which will be assigned to RECORD-FIELDS
- - Record getters with names \"record-name\"-\"field\" accepting one
-argument - the record; \"field\" is from \"record-fields\" symbols
- - Record setters with names \"record-name\"-set-\"field\" accepting two
-arguments - the record and the field value
-
-Example:
-\(ztree-defrecord person (name age))
-
-will be expanded to the following functions:
-
-\(defun person-create (name age) (...)
-\(defun person-name (record) (...)
-\(defun person-age (record) (...)
-\(defun person-set-name (record value) (...)
-\(defun person-set-age (record value) (...)
-
-To test expansion one can use GNU Emacs's pp library:
-\(require 'pp)
-\(pp-macroexpand-expression
- '(ztree-defrecord person (name age)))"
