       werl - The Erlang Emulator

       On  Windows,  the preferred way to start the Erlang system for interac-
       tive use is:

       werl <arguments>

       This will start Erlang in its own window, with fully  functioning  com-
       mand-line  editing  and  scrollbars. All flags except -oldshell work as
       they do for the erl command.

       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.

       In cases where you want to redirect standard input and/or standard out-
       put  or use Erlang in a pipeline, the werl is not suitable, and the erl
       program should be used instead.

       The werl window is in many ways modelled after the xterm window present
       on  other  platforms,  as  the xterm model fits well with line oriented
       command based interaction. This means that selecting text is line  ori-
       ented rather than rectangle oriented.

       To  select  text  in  the  werl 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
       right mouse-button. The whole area between your first selection and the
       point where you right-clicked will be included in the selection.

       The selected text is copied to the clipboard by either pressing Ctrl-C,
       using the menu or pressing the copy button in the toolbar.

       Pasted text is always inserted at the current prompt position and  will
       be interpreted by Erlang as usual keyboard input.

       Previous  command lines can be retrieved by pressing the Up arrow or by
       pressing Ctrl-P. There is also a drop down box in the toolbar  contain-
       ing  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.

       Closing the werl window will stop the Erlang emulator.
