indentation of subsection

[Remzi Seker]

Hi,
I need to have my subsections flushed to the left. I have the following 
definition:

\newlength{\mySpaceUnder}
\newlength{\mySpaceOver}
\setlength{\mySpaceUnder}{0.5ex}  % 4cm as an example ;-)
\setlength{\mySpaceOver}{5ex}   % 3cm as an example

\renewcommand\subsection{\@startsection {subsection}{1}{\z@}%
                                   {\mySpaceOver}%
                                   {\mySpaceUnder}%
                                   {\normalfont\small\mdseries\textit}}

How can I get it flushed to the left? (no indentation in the subsec title)

Thanks

Remzi
