+# V8
+
+    Stability: 1 - Experimental
+
+This module exposes events and interfaces specific to the version of [V8][]
+built with node.  These interfaces are subject to change by upstream and are
+therefore not covered under the stability index.
+
+### getHeapStatistics()
+
+Returns an object with the following properties
+
+```
+{
+  total_heap_size: 7326976,
+  total_heap_size_executable: 4194304,
+  total_physical_size: 7326976,
+  used_heap_size: 3476208,
+  heap_size_limit: 1535115264
+}
+```
+
+### setFlagsFromString()
+
+Set additional V8 command line flags.  Use with care; changing settings
+after the VM has started may result in unpredictable behavior, including
+crashes and data loss.  Or it may simply do nothing.
+
+The V8 options available for a version of node may be determined by running
+`iojs --v8-options`.  An unofficial, community-maintained list of options
+and their effects is available
+[here](https://github.com/thlorenz/v8-flags/blob/master/flags-0.11.md).
+
+Usage:
+
+```
+// Print GC events to stdout for one minute.
+var v8 = require('v8');
+v8.setFlagsFromString('--trace_gc');
+setTimeout(function() { v8.setFlagsFromString('--notrace_gc'); }, 60e3);
+```
