    Lets' hope not.

    No you don't have to.  In fact I would strongly discourage that, as I
    would also discourage you from explicitly stating the user name on
    RUNDB@pii3. 
    
    Instead use ~/.bratdbrc (more details given in the class documentation
    of BrDb).  
    
    If you really REALLY want to have an explicit user name in your
    script, I strongly encourage you to make an option 
    
      BrAppStringOption* rundbuserOption = 
        new BrAppStringOption('U', "rundb-user", 
                              "User name at the run db", "query");
      optionManager->AddOption(maindbuserOption);
    
    [This was inserted in the mail by doing M-x brat-insert-option - yes,
    I'm using Emacs to read/write mails - ofcourse :-] and then have 
    
      if (!mainDb->ConnectToRun(rundbuserOption->GetValue())) 
        return;

    Not as far as I remember. The default is to prompt the user if no
    appropiate user is found in the ~/.bratdbrc.

    Exactly my thoughts.  Djam could you please add this to The Guide
    (brat/doc/guide)?  I trust you know how to write LaTeX (not Word, RTF,
    HTML, XML, SGML, PostMill, FrontPage or other wierd formats - only
    good old (ca. 1985) - but still far better than anythinge else -
    LaTeX!!!)  
    
    In general, I'd like to encourage people to add such stuff to The
    Guide, tough I'd prefer if you'd be so kind as to send a draft (in
    LaTeX) to Kris, Flemming and me, so that we may catch
    misunderstandings and so on.  If you're uncomfortable with LaTeX
    (uh?), then please send an ASCII (not Word, RTF, HTML, XML, SGML,
    PostMill, FrontPage or other wierd formats) text instead, and we'll
    include it at a later date.  I (at least) will not read anything
    written in any other format than ASCII or LaTeX (Plain TeX included). 
    
    Yours,
