+ <description>
+ <p>On Windows, the preferred way to start the Erlang system for interactive use is:</p>
+ <p><c><![CDATA[werl <arguments>]]></c></p>
+
+ <p>This will start Erlang in its own window, with fully
+ functioning command-line editing and scrollbars. All flags
+ except <c><![CDATA[-oldshell]]></c> work as they do for
+ the <seealso marker="erl">erl</seealso> command.</p>
+
+ <p>Ctrl-C is reserved for copying text to the clipboard (Ctrl-V to paste).
+ To interrupt the runtime system or the shell process (depending on what
+ has been specified with the +B system flag), you should use Ctrl-Break.</p>
+ <p>In cases where you want to redirect standard input and/or
+ standard output or use Erlang in a pipeline, the <c>werl</c> is
+ not suitable, and the <c>erl</c> program should be used instead.</p>
+
+ <p>The <c>werl</c> window is in many ways modelled after the <c>xterm</c>
+ window present on other platforms, as the <c>xterm</c> model
+ fits well with line oriented command based interaction. This
+ means that selecting text is line oriented rather than rectangle
+ oriented.</p>
+
+ <p>To select text in the <c>werl</c> window , simply press and hold
+ the left mouse button and drag the mouse over the text you want
+ to select. If the selection crosses line boundaries, the
+ selected text will consist of complete lines where applicable
+ (just like in a word processor). To select more text than fits
+ in the window, start by selecting a small portion in the
+ beginning of the text you want, then use the scrollbar
+ to view the end of the desired selection, point to it and press
+ the <em>right</em> mouse-button. The whole area between your
+ first selection and the point where you right-clicked will be
+ included in the selection.</p>
+
+ <p>The selected text is copied to the clipboard by either
+ pressing <c>Ctrl-C</c>, using the menu or pressing the copy
+ button in the toolbar.</p>
+
+ <p>Pasted text is always inserted at the current prompt position
+ and will be interpreted by Erlang as usual keyboard input.</p>
+
+ <p>Previous command lines can be retrieved by pressing the <c>Up
+ arrow</c> or by pressing <c>Ctrl-P</c>. There is also a drop
+ down box in the toolbar containing the command
+ history. Selecting a command in the drop down box will insert it
+ at the prompt, just as if you used the keyboard to retrieve the
+ command.</p>
+
+ <p>Closing the <c>werl</c> window will stop the Erlang emulator.</p>
