+;;; Commentary:
+
+;; This library provides a flymake backend for bean-check
+;;
<https://beancount.github.io/docs/running_beancount_and_generating_reports.html#bean-check>.
+
+;; To use this library, run `flymake-bean-check-enable' in the file buffer of a
+;; beancount journal. A recommended way is to add the function to
+;; `beancount-mode-hook'.
