NAME
       LogUMS -- Write an entry to the global UMS logfile.

   SYNOPSIS
       LogUMS( login, level, format, args )
                 D2    D4      D5     D6

       LogUMS( LONG, LONG, STRPTR, LONG * );

       LogUms( login, level, format, ... )

       LogUms( LONG, LONG, STRPTR, ... )

   FUNCTION
         Write  a  short  message  to the UMS logfile, doing printf-style
       formatting on supplied parameters.
         Rather  than creating all its own logfile, an application should
       use this function to report its actions and/or errors.  This makes
       it  easier for the user to get an overview on what is happening in
       his system - he only has to look in ONE logfile.
         LogUMS()  uses  a  'level'-parameter to decide whether a message
       should  actually  be  written  to  the logfile or be ignored.  The
       lower  this  number, the more important is the message.  Choose it
       as follows:

         1-4:  an ERROR.  1=very fatal error, 4=recoverable error.
         5-7:  general information or report.
         8-9:  information that is not useful for normal operation, but
               used for debugging purposes.

         Of  course  messages with higher level-values should appear more
       frequently than those with low level-values.

   INPUTS
         level - Number between 1 and 9.
        format - Printf-style format-string.  See RawDoFmt() for more
                 information on formatting.
          args - Arguments for the format-string.
