Added Javadoc files overview.html and several package.html files.

Browse source 
Added a "Quit" option to Savant's File menu.  Factored out the Close
option in doing so.

Exceptions in many action listeners are now handled by
org.thdl.util.ThdlActionListener or org.thdl.util.ThdlAbstractAction.

Many exceptions that we used to just log now optionally cause aborts.
This option is on by default for developers using 'ant savant-run'-style
targets, but it is off for users.

An erroneous CLASSPATH now causes a useful error message in almost
all situations.

Fixed some typos and bad links in Javadoc comments.

Added a simple assertion facility, but the overhead is suffered even in
release builds.

Factored out the code that sets up log files like savant.log and jskad.log.

Subject: Exception in event handlers
View this article only
Newsgroups: comp.lang.java.gui, comp.lang.java.help, comp.lang.java.programmer
Date: 1998/07/07
Hi everyone !
I've got a wee question regarding propagation of exceptions in event
handlers :
here's the fun :
Say, you've got a method A() that is called from within an event handler
(mostly it'll be in actionPerformed(ActionEvent) from ActionListener
interface).
Now this A() method produces an exception. This exception will be propagated
up to the caller of actionPerformed which is into the event handler queue.
This exception never gets propagated higher than the handler (and produces a
message "exception occured in event handler")
Now I would like this exception NOT to be caught there but to propagate
until the program terminates or it is caught somewhere else.
Is there a way to do that ? There's no mean to re-throw that exception as
the event handler is part of the core java.
Basically what I would like to do is catch ANY exception that occurs in a
java application in order to display a message box, without having to put
try{} catch{} blocks all other the place...
Thanks for any help on that
Chunk of code to illustrate :
class MyClass extends Object implements ActionListener {
// blah blah
public void actionPerformed(ActionEvent event) {
A(); //May throw an exception here but the actionPerformed is called
// from the event handler and the exception is caught into it
//So the actionPerformed finishes because of the exception but the
// rest of the app is likely to be in an unstable state, but still running
}
// So here the exception has been caught without an explicit try{}
// catch{} WHICH I DONT WANT
//You then can happily do something else....even if A() failed....
}//MyClass

Once an exception is caught it is up to the catcher what to do with it. The
event dispatch thread simply catches the exception and tells you about it.
There is no way to make this exception go any further - indeed there is
nowhere further for it to go. Exceptions occur per-thread and if the thread
doesn't catch it the thread will terminate. A more sophisticated event
mechanism might allow you to register a handler/listener to take some
action when this occurred but the current AWT does not.

Summary:THDL Projects and Goals
</pre>
<p>
Hello. You'll see that we at the Tibetan and Himalayan Digital Library
have been developing several Tibetan language and culture related
software tools, all of which take advantage of Tony Duff's free
cross-platform TibetanMachineWeb fonts. We think these tools have
reached a level of development that they now need the active
participation of the larger programming community in order to
progress.
</p>
<p>
On the one hand, we've developed Java-based tools for inputting and
displaying Tibetan script (Jskad), as well as for the transcription of
Tibetan-language videos (QuillDriver), and the synchronized playback
of videos along with their associated transcripts (Savant).
</p>
<p>
On the other hand, recognizing the ubiquity of Word, we've also
developed Visual Basic macros for inputting Tibetan script (WylieWord)
and diacritics useful for Asian studies (DiacriticsForWord,
DiacriticsForWin2k) into Microsoft Word.
</p>
<p>
The Java side of our project has several goals. First, we'd like to
create a high quality cross-platform word processor/display engine
optimized for Tibetan script input and display. This probably means
embedding Jskad in an established open source text editor.
</p>
<p>
Second, we are developing educational and research-oriented software
that takes advantage of these basic Tibetan display
capabilities. QuillDriver, designed for transcription of videos, and
Savant, an integrated tool for learning language from digital video,
are examples of this. Here, several tasks are on the horizon: merging
QuillDriver and Savant into the same tool, which has both edit
(QuillDriver) and display (Savant) modes; and integrating both with
Tibetan dictionary, grammar and pedagogy modules also being developed
at the THDL. Finally, note that unlike Jskad, both QuillDriver and
Savant are meant to be truly multilingual, and not just specialized
Tibetan software.
</p>
<p>
Still, we know that no matter what the open source community does,
Microsoft Word will still remain the most dominant (and arguably the
best) word-processor. There will always be people, and always
occasions, to type Tibetan into Word. Therefore, we are also pushing
our Visual Basic macros for Tibetan and diacritic input. Our main
goals with these tools is to make them as bug-free and user-friendly
as possible, and to develop stable Mac versions. Another possible goal
would be to extend these tools to work with other Office applications,
such as Excel or Access.
</p>
<p>
Given the various projects, we are setting up several forums for
specialized discussion:
</p>
<p>
1) General
2) Jskad
3) QuillDriver/Savant
4) WylieWord
5) Diacritics
</p>
<p>
Please occasionally consult those forums of interest to you. Also,
please take a look at the mailing lists and subscribe to those you
want to follow.
