draw a synteny map - any software available (Nov/03/2009 )

Dear all,
I just constructed a genetic map for cowpea and want to draw a synteny map with the published model legume genetic map.
many published documents contain some very beautiful syteny map but I don't know how to make such a map? by hand or there are already softwares to aid this?
Thanks very much for any of your answers!
Blessings!

you can try Bluejay, its for free and you can download it from this link . I once heard a talk about that software and it should be able to draw synteny maps but i did not used it so far for such a task!

Regards,
