+ * This thread module exports the following types:

+ * _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.
