+\begin{abstract}
+This is the {\em blue manual}, describing the data formats of the dvdisaster
+Reed-Solomon codecs which are currently called RS01, RS02 and RS03.
+The codecs create Reed-Solomon parity data to protect data stored on optical media.
+Depending on the codec, parity data can either be stored in a separate file 
+or be integrated with the .iso image on the same medium. 
+See \url{http://dvdisaster.org}  for additional resources on the dvdisaster project,
+e.g. for the {\em orange manual} (manual.pdf) containing information for end users.
+\end{abstract}

+
+{\bf Target audience.} This paper is primarily intended as a working base for the
+dvdisaster developers and, when the final version has been crafted, as an implementation
+guide for third party developers who wish to create and process dvdisaster error correction data.
+It is {\bf neither intended nor suitable} as end-user documentation; for usage information
+please refer to the online documentation at \url{http://dvdisaster.org}.
+
+\bigskip
+
+{\bf Prerequisites.} This paper assumes profound knowledge of coding theory and the 
+underlying math. The reader is assumed to have a thorough understanding of Reed-Solomon
+codes, both in theory and from an implementation viewpoint. A basic understanding
+of programming in C is also assumed.
