NAME
     xbiff - mailbox flag for X

SYNOPSIS
     xbiff [-toolkitoption ...] [-option ...]

DESCRIPTION
     The xbiff program displays a  little  image  of  a  mailbox.
     When  there  is  no  mail,  the flag on the mailbox is down.
     When mail arrives, the flag goes up and the  mailbox  beeps.
     By  default,  pressing  any mouse button in the image forces
     xbiff to remember the current size of the mail file as being
     the ``empty'' size and to lower the flag.

     This program is nothing  more  than  a  wrapper  around  the
     Athena Mailbox widget.

OPTIONS
     Xbiff accepts all of the standard  X  Toolkit  command  line
     options along with the additional options listed below:

     -help   This option indicates that a brief  summary  of  the
             allowed  options  should  be printed on the standard
             error.

     -update seconds
             This option specifies the frequency  in  seconds  at
             which xbiff should update its display.  If the mail-
             box is obscured and then exposed, it will be updated
             immediately.  The default is 30 seconds.

     -file filename
             This option specifies the name  of  the  file  which
             should   be   monitored.   By  default,  it  watches
             /var/mail/username, where  username  is  your  login
             name.

     -volume percentage
             This option specifies how loud the  bell  should  be
             rung when new mail comes in.

     -shape  This option indicates that the mailbox window should
             be  shaped if masks for the empty or full images are
             given.

     The following standard X Toolkit command line arguments  are
     commonly used with xbiff:

     -display display
             This option specifies the X server to contact.

     -geometry geometry
             This option specifies the preferred size  and  posi-
             tion  of the mailbox window.  The mailbox is 48 pix-
             els wide and 48 pixels high and will be centered  in
             the window.

     -bg color
             This option specifies the color to use for the back-
             ground of the window.

     -bd color
             This option specifies  the  color  to  use  for  the
             border of the window.

     -bw number
             This option specifies the width  in  pixels  of  the
             border surrounding the window.

     -fg color
             This option specifies the color to use for the fore-
             ground of the window.

     -rv     This option indicates that reverse video  should  be
             simulated  by swapping the foreground and background
             colors.

     -xrm resourcestring
             This option specifies a resource string to be  used.
             This is especially useful for setting resources that
             do not have separate command line options.

X DEFAULTS
     The application class name is XBiff.  This program uses  the
     Mailbox widget in the Athena widget set.  It understands all
     of the core resource names and classes as well as:

     checkCommand (class CheckCommand)
             Specifies a shell command to be  executed  to  check
             for new mail rather than examining the size of file.
             The specified string value is used as  the  argument
             to  a  system(3)  call and may therefore contain i/o
             redirection.  An exit status of 0 indicates that new
             mail  is waiting, 1 indicates that there has been no
             change in size, and 2 indicates that  the  mail  has
             been  cleared.  By default, no shell command is pro-
             vided.

     file    (class File)
             Specifies the name  of  the  file  to  monitor.  The
             default  is to watch /var/mail/username, where user-
             name is your login name.

     onceOnly
             (class Boolean)
             Specifies that the bell is only rung the first  time
             new  mail  is  found  and is not rung again until at
             least one interval has passed with no mail  waiting.
             The window will continue to indicate the presence of
             new mail until it has been retrieved.   The  default
             is false.

     width   (class Width)
             Specifies the width of the mailbox.

     height  (class Height)
             Specifies the height of the mailbox.

     update  (class Interval) Specifies the frequency in  seconds
             at which the mail should be checked.  The default is
             30.

     volume  (class Volume)
             Specifies how loud the bell  should  be  rung.   The
             default is 33 percent.

     foreground
             (class Foreground)
             Specifies the color for the foreground.

     reverseVideo
             (class ReverseVideo)
             Specifies that the foreground and background  should
             be reversed.

     flip    (class Flip)
             Specifies whether or not the  image  that  is  shown
             when  mail  has  arrived  should  be  inverted.  The
             default is ``true.''

     fullPixmap
             (class Pixmap)
             Specifies a bitmap to be shown  when  new  mail  has
             arrived.  The default is flagup.

     emptyPixmap
             (class Pixmap)
             Specifies a bitmap to be shown when no new  mail  is
             present.  The default is flagdown.

     shapeWindow
             (class ShapeWindow)
             Specifies whether or not the mailbox  window  should
             be  shaped to the given fullPixmapMask and emptyPix-
             mapMask.  The default is false.

     fullPixmapMask
             (class PixmapMask)
             Specifies a mask for the bitmap to be shown when new
             mail has arrived.  The default is none.

     emptyPixmapMask
             (class PixmapMask)
             Specifies a mask for the bitmap to be shown when  no
             new mail is present.  The default is none.

ACTIONS
     The Mailbox widget provides the following actions for use in
     event translations:

     check() This action causes the widget to check for new  mail
             and display the flag appropriately.

     unset() This action causes the  widget  to  lower  the  flag
             until new mail comes in.

     set()   This action causes the  widget  to  raise  the  flag
             until the user resets it.

     The default translation is
             <ButtonPress>:  unset()

ENVIRONMENT
     DISPLAY to get the default host and display number.

     XENVIRONMENT
             to get the name of a resource  file  that  overrides
             the  global resources stored in the RESOURCE_MANAGER
             property.
