Opening packages using scheme

[Gautham Anil <gautham_anil@cse.iitb.ac.in>]

Hi,

I need to find out how I can open packages opened using ,open such as 
,open sockets etc. in the program itself.
So a program could be something like

(begin
  (run-shell (,open sockets))
  (run-shell (,open locks))
  (run-shell (,open threads))
  ....
)

Thanks in advance.
