+/**
+ * \file glheader.h
+ * Top-most include file.
+ *
+ * This is the top-most include file of the Mesa sources.
+ * It includes gl.h and all system headers which are needed.
+ * Other Mesa source files should \e not directly include any system
+ * headers. This allows Mesa to be integrated into XFree86 and
+ * allows system-dependent hacks/workarounds to be collected in one place.
+ *
+ * \note Actually, a lot of system-dependent stuff is now in imports.[ch].
+ *
+ * If you touch this file, everything gets recompiled!
+ *
+ * This file should be included before any other header in the .c files.
+ *
+ * Put compiler/OS/assembly pragmas and macros here to avoid
+ * cluttering other source files.
