 \section intro_sec Introduction

 Open Source CPAP Analysis Reporter (OSCAR) is a program derived from the SleepyHead program written by Mark Watkins.

 SleepyHead was a Cross-Platform Open-Source software for reviewing data from %CPAP devices, which are used in the treatment of Sleep Disorders.

 SleepyHead was created by Mark Watkins, an Australian software developer.

 This document is an attempt to provide a little technical insight into OSCAR's program internals.

 \section project_info Further Information
 OSCAR is hosted on <a href="https://gitlab.com/pholy/OSCAR-code">Gitlab</a> with full source code available there.

 Help for users can be found in the <a href="http://www.apneaboard.com/wiki/index.php?title=OSCAR_Help">OSCAR Help Wiki</a>.

 Data structures are described in a <a href="http://www.apneaboard.com/wiki/index.php?title=OSCAR_Data_Information">OSCAR Data Information Wiki</a>.


 \section structure Program Structure
 OSCAR is written in C++ using Qt Toolkit library, and comprises of 3 main components
 \list
 \li The SleepLib Database, a specialized database for working with multiple sources of Sleep device data.
 \li A custom designed, high performance and interactive OpenGL Graphing Library.
 \li and the main Application user interface.
 \endlist

 This document is still a work in progress, right now all the classes and sections are jumbled together.
