@section General

This output module outputs the contents of all sections in Motorola srecord
format, which is a simple ASCII output of hexadecimal digits. Each record
starts with '@code{S}' and a one-digit ID. It is followed by the data
and terminated by a checksum and a newline character.
Every section starts with a new header record.
