This document describes the FSX format for autogen (AGN) files. This description is not yet complete, so feel free to add more information if you have any.

== Sections ==

The AGN file uses the RIFF format, this means that the file consists of different sections. Each section starts with a four character label, followed by the size of the content in bytes (this size is thus without the length of the header itself).

The main RIFF section itself has one additional parameter, this is a four character string that indicates the type of RIFF AGN file. For an FSX AGN file the value should always be AGNX.

The following subsection show more details about the content of these different sections.
