+ * @file
+ * Thread
+ *
+ * Initial version by John Stone (j.stone@acm.org) (johns@cs.umr.edu)
+ *                and Christoph Poliwoda (poliwoda@volumegraphics.com)
+ * Revised by Keith Whitwell
+ * Adapted for new gl dispatcher by Brian Paul
+ *
+ *
+ *
+ * DOCUMENTATION
+ *
+ * This thread module exports the following types:
+ *   _glthread_TSD     Thread-specific data area
+ *   _glthread_Thread  Thread datatype
+ *   _glthread_Mutex   Mutual exclusion lock
+ *
+ * Macros:
+ *   _glthread_DECLARE_STATIC_MUTEX(name)   Declare a non-local mutex
+ *   _glthread_INIT_MUTEX(name)             Initialize a mutex
+ *   _glthread_LOCK_MUTEX(name)             Lock a mutex
+ *   _glthread_UNLOCK_MUTEX(name)           Unlock a mutex
+ *
+ * Functions:
+ *   _glthread_GetID(v)      Get integer thread ID
+ *   _glthread_InitTSD()     Initialize thread-specific data
+ *   _glthread_GetTSD()      Get thread-specific data
+ *   _glthread_SetTSD()      Set thread-specific data
+ *
+ * If this file is accidentally included by a non-threaded build,
+ * it should not cause the build to fail, or otherwise cause problems.
+ * In general, it should only be included when needed however.
