\FirstLine{The first line of this paragraph is
           typeset in boldface.}
The remainder is set in the normal body font.

\FirstLine{\noindent Less material} in the argument
will be fully typeset in the special font. Note the
placement and result of the \verb=\noindent= command.

\noindent\FirstLine{If placed in front it will get
lost} as you can see here.
