+/** @file
+    Provides simple diagnostic support.
+
+    @deprecated
+    The facilities provided by this header are deprecated.  True assertions
+    (that detect broken program logic) should use standard assert (which aborts
+    if an assertion fails, and is controlled by the standard NDEBUG macro).
+    Logging of warnings (e.g., about malformed input) and traces (e.g., about
+    steps taken while executing some protocol) should use the facilities
+    provided by (C++ only) sal/log.hxx.
+
+    Because the assertion macros (OSL_ASSERT, OSL_ENSURE, OSL_FAIL, OSL_PRECOND,
+    and OSL_POSTCOND) have been used for true assertions as well as for logged
+    warnings, they map to SAL_WARN instead of standard assert.  OSL_TRACE maps
+    to SAL_INFO.
+
+    The functions defined in this header are not intended to be used directly,
+    but through defined macros. The macros can be divided into three categories:
+    assertions, traces and other stuff .-) Their usability depends on the value
+    of OSL_DEBUG_LEVEL macro: assertions are only active if OSL_DEBUG_LEVEL is 1
+    or greater, traces if OSL_DEBUG_LEVEL is 2 or greater.
+
+    Traces:
+    OSL_TRACE(fmt, args...)
+        Prints trace message. The arguments have the same meaning as the
+        arguments of printf.
