How can I increase the margins of my Abstract page

[neo]

Dear LaTeX users,

I would like to increase the margins on my abstract page (between
\begin{abstract} and \end{abstract} only). How can I easily achieve
this ?

Many thanks
Tolga

The chngpage package:

http://www.tug.org/tex-archive/help/Catalogue/entries/chngpage.html

can achieve this ... but, depending on how you want to change the
margins, and where your abstract is, it might be easier to just use
\vspace*{} and/or \hspace*{} ... but, chngpage is very robust, and has
lots of options.
