CGAL users discussion list

Dear Xiangzhi

(note that the title of your message was not really consistent with its 
contents)

You will find the list of all CGAL packages in the CGAL web site.
More precisely there are links to there:
http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/packages.html
and to the table of contents there:
http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/contents.html

As you can see on these pages, there is a chapter named
"2D Straight Skeleton and Polygon Offsetting"
that could help you.
