-- Error Entries in a temporary file.
--
-- A file of error entries behaves like any other standard
-- file - it may be created, written to, reset, read from and
-- closed in the standard way.
--
-- The implementation of this package _may_ choose to store
-- these files on disk, using the facilities of SPARK_IO, or
-- may choose to store the file entirely in-memory on some
-- hosts.
