- * All source files except skge.c, skdrv1st.h, skdrv2nd.h and sktypes.h

- * Those are used for drivers on multiple OS', so some thing may seem
- * unnecessary complicated on Linux. Please do not try to 'clean up'
- * them without VERY good reasons, because this will make it more
- * difficult to keep the Linux driver in synchronisation with the
- * other versions.
- *
- * Include file hierarchy:
