+/**
+ * Terminal implementation for Microsoft Windows. Terminal initialization in
+ * {@link #init} is accomplished by extracting the
+ * <em>jline_<i>version</i>.dll</em>, saving it to the system temporary
+ * directoy (determined by the setting of the <em>java.io.tmpdir</em> System
+ * property), loading the library, and then calling the Win32 APIs <a
+ * href="http://msdn.microsoft.com/library/default.asp?
+ * url=/library/en-us/dllproc/base/setconsolemode.asp">SetConsoleMode</a> and
+ * <a href="http://msdn.microsoft.com/library/default.asp?
+ * url=/library/en-us/dllproc/base/getconsolemode.asp">GetConsoleMode</a> to
+ * disable character echoing.
+ * <p/>
+ * <p>
+ * By default, the {@link #wrapInIfNeeded(java.io.InputStream)} method will attempt
+ * to test to see if the specified {@link InputStream} is {@link System#in} or a wrapper
+ * around {@link FileDescriptor#in}, and if so, will bypass the character reading to
+ * directly invoke the readc() method in the JNI library. This is so the class
+ * can read special keys (like arrow keys) which are otherwise inaccessible via
+ * the {@link System#in} stream. Using JNI reading can be bypassed by setting
+ * the <code>jline.WindowsTerminal.directConsole</code> system property
+ * to <code>false</code>.
