========================version 1.0==================================
xwall/xwalld is the client/server implemetation of the xwall protocol.
you can integrate it into your xdm(1) login. i have ported it on my
solaris 2.5 machines. but it is also easily to port on other os by
minor modification.

why need this ware?
    when user logins through xdm(1), there may be no tty associated
with his/her x session. so wall(1) won't work for this case. xwall
is only a suppliment for wall(1). it is, however, not supposed
to be a replacement for wall(1). but it is very easy to integrate xwall
with wall(1) through a shell script so that you don't have to
type the same message twice.

this package is developped by myself. it does nothing with the 
existing xwall of someone else. this is why i name it as 'txwall'. 
but the executalbles share the same name. after 'make install', 
you will get
      xwalld    --  server running as daemon
      xwall     --  client
      xwall(1)  --  man page for xwall/xwalld.
      xwall(5)  --  man page for xwall protocol
     alwall     --  a wrapper to integrate wall and xwall.

NOTE: if you have already installed somebody else's xwall package,
      please save it before install this one. or change the names
      of mine.

the xwall is a set-gid file. so you need to change its mode and
owner after you install it. see xwall(1) for more information.

to install:
    modify the makefile
    make install

to integrate it into xdm(1), see the xwall(1).
