  * Helper class for systrace (see http://developer.android.com/tools/help/systrace.html).<p>
  * To enable, set log.tag.Bugle_Trace (defined by {@link #TAG} to VERBOSE before
  * the process starts.<p>
- * Note that this will run only on JBMR2 or later; on earlier platforms or if the log
- * tag isn't set, calls to {@link #beginSection(String)} or {@link #endSection()} are no-ops. <p>
- * Internally, calls dispatch to either a class that actually does work or a class that doesn't.
- * This avoids Dalvik complaining when it loads the class on earlier platforms that the
- * opcodes aren't available, and, according to the Dalvik team, using vtable dispatching for
- * something like this should be faster than if (OsUtil.isAtLeast...()) on each call.
