Annex C. Error catalogue syntax

The following gives a summary of the syntax for the error catalogue accepted by the make_err tool. Identifiers are normal C-style identifiers, strings consist of any sequence of characters enclosed inside "....". The escape sequences \" and \\ are allowed in strings; other characters (including newline characters) map to themselves. C-style comments are allowed.
