+/**
+ * This package contains annotations and enumerations that are used to
+ * add DTrace-specific information to a tracing provider.
+ * <p>
+ * The DTrace-specific annotations modify the attributes of a DTrace provider
+ * implementation when it is used by the tracing subsystem.  The annotations are
+ * added to a {@code com.sun.tracing} provider specification to control
+ * specific attributes of the provider as it relates to DTrace.
+ * <p>
+ * Any other tracing subsystems supported by the system will ignore these
+ * annotations.
+ * <p>
+ * DTrace probes have additional fields and stability attributes that are
+ * not accounted for in the generic tracing package.  If unspecified, the
+ * default values are used for the stability and dependency attributes of
+ * probes, as well as for the module and field names of the generated probes.
+ * The values can be specified by adding the appropriate annotations to the
+ * provider specification.
+ * <p>
+ * The {@code FunctionName} annotation is used to annotate the tracepoint
+ * methods defined in the provider specification.  The value of this annotation
+ * is used as the {@code function} field in the generated DTrace probes. It
+ * is typically set to the name of the enclosing function where the
+ * tracepoint is triggered.
+ * <p>
+ * The {@code ModuleName} annotation is used to annotate the provider
+ * specification itself and applies to all the probes in the provider.  It
+ * sets the value of the {@code module} field in the generated DTrace probes.
+ * <p>
+ * The remaining annotations, are also applied to the provider itself, and
+ * are used to set the stability and dependency attributes of all probes in
+ * that provider.  Each probe field and the probe arguments can be
+ * independently assigned interface attributes to control the stability
+ * ratings of the probes.
+ * <p>
+ * Here is an example of how to declare a provider, specifying additional DTrace
+ * data:
+<PRE>
+    &#064;ProviderName("my_app_provider")
+    &#064;ModuleName("app.jar")
+    &#064;ProviderAttributes(&#064;Attributes={
+        name=StabilityLevel.STABLE,data=StabilityLevel.STABLE,
+        dependency=DependencyClass.COMMON})
+    &#064;ProbeAttributes(&#064;Attributes={
+        name=StabilityLevel.STABLE,data=StabilityLevel.STABLE,
+        dependency=DependencyClass.COMMON})
+    &#064;ModuleAttributes(&#064;Attributes={name=StabilityLevel.UNSTABLE})
+    public class MyProvider {
+        &#064;FunctionName("main") void startProbe();
+    }
+</PRE>
