CVS:How tocontrol privileges for a special developer?

[xiangbin]

Hi,all
I am a new comer to CVS.
Now I wonder if I can control the privileges of a special directory(or a
file) for a special developer .
For example:
user                  directory                         privileges
tom                 myproject/sources
checkout,checkin,add,remove
                  myproject/PJadmin             no privileges
                  myproject/PJstatus            checkout

stevens            myproject/sources
checkout,checkin,add,remove
                  myproject/PJadmin             checkout,checkin,add,remove
                  myproject/PJstatus            checkout

alen                myproject/sources                       checkout
                  myproject/PJadmin             checkout
                  myproject/PJstatus            checkout,checkin,add,remove

Could CVS be able to do this?
