 NAME
       multixterm - drive multiple xterms separately or together

 SYNOPSIS
       multixterm [-xa "xterm args"]
                  [-xc "command"]
                  [-xd "directory"]
                  [-xf "file"]
                  [-xn "xterm names"]
                  [-xv] (enable verbose mode)
                  [-xh] or [-x?] (help)
                  [xterm names or user-defined args...]

 DESCRIPTION
       Multixterm creates multiple xterms that can be driven together
       or separately.

       In its simplest form, multixterm is run with no arguments and
       commands are interactively entered in the first entry field.
       Press return (or click the "new xterm" button) to create a new
       xterm running that command.

       Keystrokes in the "stdin window" are redirected to all xterms
       started by multixterm.  xterms may be driven separately simply
       by focusing on them.

       The stdin window must have the focus for keystrokes to be sent
       to the xterms.  When it has the focus, the color changes to
       aquamarine.  As characters are entered, the color changes to
       green for a second.  This provides feedback since characters
       are not echoed in the stdin window.

       Typing in the stdin window while holding down the alt or meta
       keys sends an escape character before the typed characters.
       This provides support for programs such as emacs.
