CCL: Free molecular builder

 Sent to CCL by: "Sherin  Alfalah" [shireen.alfalah .]
 Dear CCL users,
 I am wondering if there is a free and practical molecular builder that runs on
 Windows linux platforms. It would be very nice if there is one that runs on both
 platforms at the same time.
 Thanks in advance.
