+ * LLCond encapsulates the pattern required to use a condition_variable. It
+ * bundles subject data, a mutex and a condition_variable: the three required
+ * data objects. It provides wait() methods analogous to condition_variable,
+ * but using the contained condition_variable and the contained mutex. It
+ * provides modify() methods accepting an invocable to safely modify the
+ * contained data and notify waiters. These methods implicitly perform the
+ * required locking.
+ *
+ * The generic LLCond template assumes that DATA might be a struct or class.
+ * For a scalar DATA type, consider LLScalarCond instead. For specifically
+ * bool, consider LLBoolCond.
+ *
+ * Use of LLCoros::ConditionVariable makes LLCond work between
+ * coroutines as well as between threads.

- * overload exists because certain event APIs are defined in terms of a reply
- * LLEventPump and an error LLEventPump.
- *
- * The LLEventWithID return value provides not only the received event, but
- * the index of the pump on which it arrived (0 or 1).
- *
- * @note
- * I'd have preferred to overload the name postAndSuspend() for both signatures.
- * But consider the following ambiguous call:
- * @code
- * postAndSuspend(LLSD(), requestPump, replyPump, "someString");
- * @endcode
- * "someString" could be converted to either LLSD (@a replyPumpNamePath for
- * the single-pump function) or LLEventOrPumpName (@a replyPump1 for two-pump
- * function).

-/**
- * We originally provided a suite of overloaded
- * LLEventTrackable::listenTo(LLEventPump&, ...) methods that would call
- * LLEventPump::listen(...) and then pass the returned LLBoundListener to
- * LLEventTrackable::track(). This was workable but error-prone: the coder
- * must remember to call listenTo() rather than the more straightforward
- * listen() method.
- *
- * Now we publish only the single canonical listen() method, so there's a
- * uniform mechanism. Having a single way to do this is good, in that there's
- * no question in the coder's mind which of several alternatives to choose.
- *
- * To support automatic connection management, we use boost::visit_each
- * (http://www.boost.org/doc/libs/1_37_0/doc/html/boost/visit_each.html) to
- * inspect each argument of a boost::bind expression. (Although the visit_each
- * mechanism was first introduced with the original Boost.Signals library, it
- * was only later documented.)
- *
- * Cases:
- * * At least one of the function's arguments is a boost::weak_ptr<T>. Pass
- *   the corresponding shared_ptr to slot_type::track(). Ideally that would be
- *   the object whose method we want to call, but in fact we do the same for
- *   any weak_ptr we might find among the bound arguments. If we're passing
- *   our bound method a weak_ptr to some object, wouldn't the destruction of
- *   that object invalidate the call? So we disconnect automatically when any
- *   such object is destroyed. This is the mechanism preferred by boost::
- *   signals2.
- * * One of the functions's arguments is a boost::shared_ptr<T>. This produces
- *   a compile error: the bound copy of the shared_ptr stored in the
- *   boost_bind object stored in the signal object would make the referenced
- *   T object immortal. We provide a weaken() function. Pass
- *   weaken(your_shared_ptr) instead. (We can inspect, but not modify, the
- *   boost::bind object. Otherwise we'd replace the shared_ptr with weak_ptr
- *   implicitly and just proceed.)
- * * One of the function's arguments is a plain pointer/reference to an object
- *   derived from boost::enable_shared_from_this. We assume that this object
- *   is managed using boost::shared_ptr, so we implicitly extract a shared_ptr
- *   and track that. (UNDER CONSTRUCTION)
- * * One of the function's arguments is derived from LLEventTrackable. Pass
- *   the LLBoundListener to its LLEventTrackable::track(). This is vulnerable
- *   to a couple different race conditions, as described in LLEventTrackable
- *   documentation. (NOTE: Now that LLEventTrackable is a typedef for
- *   boost::signals2::trackable, the Signals2 library handles this itself, so
- *   our visitor needs no special logic for this case.)
- * * Any other argument type is irrelevant to automatic connection management.

+ * LLMessageSystem::mMessageReader, assuming that all subsequent processing of
+ * the current message will use the same mMessageReader value -- only to have
+ * a different coroutine sneak in and replace mMessageReader before
+ * completion. This is a limitation of sharing a stateful global resource for
+ * message parsing; instead code receiving a new message should instantiate a
+ * (trivially constructed) local message parser and use that.
+ *
+ * Until then, when one coroutine sets a particular LLMessageReader subclass
+ * as the current message reader, ensure that no other coroutine can replace
+ * it until the first coroutine has finished with its message.
+ *
+ * This is achieved with two helper classes. LLMessageSystem::mMessageReader
+ * is now an LLMessageReaderPointer instance, which can efficiently compare or
+ * dereference its contained LLMessageReader* but which cannot be directly
+ * assigned. To change the value of LLMessageReaderPointer, you must
+ * instantiate LockMessageReader with the LLMessageReader* you wish to make
+ * current. mMessageReader will have that value for the lifetime of the
+ * LockMessageReader instance, then revert to nullptr. Moreover, as its name
+ * implies, LockMessageReader locks the mutex in LLMessageReaderPointer so
+ * that any other coroutine instantiating LockMessageReader will block until

+ * parameters directly. We will expose them via Debug Settings and that should
+ * let us iterate on a collection of values that work for us. Hopefully! 
+ *
+ * From the VIVOX Docs:
+ *
+ * VadAuto: A flag indicating if the automatic VAD is enabled (1) or disabled (0)
+ *
+ * VadHangover: The time (in milliseconds) that it takes
+ * for the VAD to switch back to silence from speech mode after the last speech
+ * frame has been detected.
+ *
+ * VadNoiseFloor: A dimensionless value between 0 and 
+ * 20000 (default 576) that controls the maximum level at which the noise floor
+ * may be set at by the VAD's noise tracking. Too low of a value will make noise
+ * tracking ineffective (A value of 0 disables noise tracking and the VAD then 
+ * relies purely on the sensitivity property). Too high of a value will make 
+ * long speech classifiable as noise.
+ *
+ * VadSensitivity: A dimensionless value between 0 and 
+ * 100, indicating the 'sensitivity of the VAD'. Increasing this value corresponds
+ * to decreasing the sensitivity of the VAD (i.e. '0' is most sensitive, 
+ * while 100 is 'least sensitive')

+Analyze the XUI configuration files to find text that may need to
+be translated. Works by comparing two specified revisions, one
+specified by --rev (default HEAD) and one specified by --rev_base
+(default master). The script works by comparing xui contents of the
+two revisions, and outputs a spreadsheet listing any areas of
+difference. The target language must be specified using the --lang
+option. Output is an excel file, which can be used as-is or imported
+into google sheets.
+
+If the --rev revision already contains a translation for the text, it
+will be included in the spreadsheet for reference.
+    
+Normally you would want --rev_base to be the last revision to have
+translations added, and --rev to be the tip of the current
+project. You can find the last commit with translation work using "git log --grep INTL- | head"
+
+The --missing argument can be used to find all text with missing
+translations, regardless of when it was added. If translations are being kept
+reasonably current, you will normally not need this argument.
