Undocumented routines:
----------------------

  ipcsinit( "name" )
      Registers your ipcs name within the local cell.

  setname( "name" )
      Change your ipcs name.  Not sure why we do this, but it's
      shown in the example below.

  cell_reg()
      Registers your ipcsName with your cell mailer so you can receive
      incoming mail from outside your cell.

----------------------------------
  From the demo program receiver.c:

          sts = ipcsinit("");
          if (sts & 1)
             sts = setname(ipcsName);
          if (sts & 1)
             sts = cell_reg();
          if (~sts & 1)
              exit(ipcsmsg(sts,"*ERR* from ipcsinit for '%s'",ipcsName));
