+In the CLI, execute them to see the error messages (`./showall`).
 
+In Emacs with [flycheck-hledger][],

+and open the files to see how flycheck handles them.
+Some files contain extra declarations to ease flycheck testing.

-errors is a big project.
-But (once we converge on a standard format) it's quite crowd-sourceable, 
-tackling each error separately, and any progress means immediate practical benefits.
