[Orgmode] No title or date in LaTeX export

[Xin Shi]

Hello Experts,

When I export the org file to LaTeX, I want no title or date in the first page.  Namely, I want these lines to be commented out:

%\title{XXXXXX}

%\date{XXXXX}

%\maketitle 

So far, I only found

#+OPTIONS: author:nil  can make:

%\author{XXXX} 

I also tried :

# Local Variables:

# org-export-latex-title-command: " "

# End:

but still saw the \maketitle .

Any suggestions?

Thanks!

Xin
