This library implements a text-based windowing system reminiscient of
Borland's [Turbo Vision](http://en.wikipedia.org/wiki/Turbo_Vision)
system. (For those wishing to use the actual C++ Turbo Vision
-library, see [Sergio Sigala's C++ version based on the public domain
-sources released by Borland.](http://tvision.sourceforge.net/) )

Jexer currently supports three backends:
sequences generated by the library itself: ncurses is not required
or linked to. xterm mouse tracking using UTF8 and SGR coordinates
are supported. For the demo application, this is the default
- backend on non-Windows platforms.
+ backend on non-Windows/non-Mac platforms.
* The same command-line ECMA-48 / ANSI X3.64 type terminal as above,
but to any general InputStream/OutputStream or Reader/Writer. See
character encoding than the default UTF-8.
* Java Swing UI. This backend can be selected by setting
- jexer.Swing=true. The default window size for Swing is 132x40,
- which is set in jexer.session.SwingSession. For the demo
- application, this is the default backend on Windows platforms.
+ jexer.Swing=true. The default window size for Swing is 80x25, which
+ is set in jexer.session.SwingSession. For the demo application,
+ this is the default backend on Windows and Mac platforms.
Additional backends can be created by subclassing
jexer.backend.Backend and passing it into the TApplication
constructor.

Used by jexer.io.SwingScreen. Selects the cursor style to draw.
Valid values are: underline, block, outline. Default: underline.

+ Used by jexer.io.SwingScreen. If false, use naive Swing thread

Known Issues / Arbitrary Decisions
obviously expected behavior did not happen or when a specification was
ambiguous. This section describes such issues.
- - TTerminalWindow will hang on input from the remote if the
- TApplication is exited before the TTerminalWindow's process has
- closed on its own. This is due to a Java limitation/interaction
- between blocking reads (which is necessary to get UTF8 translation
- correct) and file streams.

- See jexer.tterminal.ECMA48 for more specifics of terminal
emulation limitations.
input (see the ENABLE_LINE_INPUT flag for GetConsoleMode() and
SetConsoleMode()).
- - TTerminalWindow launches 'script -fqe /dev/null' on non-Windows
- platforms. This is a workaround for the C library behavior of
- checking for a tty: script launches $SHELL in a pseudo-tty. This
- works on Linux but might not on other Posix-y platforms.
