/** @file
* @ingroup aof
*
* AOF message codec.
*
* It provides various AOF encoding and decoding functions, and implements
* dba_file reading and writing of AOF files.
*
* AOF records can be read, written and interpreted into a dba_msg. Encoding
* from a dba_msg is not yet implemented. A "makeaof" tool exists, not part of
* DB-All.e, that can convert BUFR messages into AOF.
*
* Endianness of the written records can be controlled by the environment
* variable DBA_AOF_ENDIANNESS:
*
* \li \b ARCH writes using the host endianness
* \li \n LE writes using little endian
* \li \n BE writes using big endian
*
* If the environment variable is not set, the default is to write using the
* host endianness.
