I have a big project with the following structure :

BigProject-+-Project_A-+-Prj_1 (User A,B,C Read only)
| +-Prj_2 (User A,B,C Read only)
| +_Prj_3 (User A,B Read only)
|
+-Project_B-+-Prj_4 (User B R/W other denny)
| +-Prj_5 (User A R/W other denny)
| +_Prj_6 (User C R/W other denny)
|
+-Project_C-+-Prj_7 (User A (R/W), B (R))
+-Prj_8 (User B (R/W), C,A (R))
+_Prj_9 (User A Read only)

Can I setup the permission for User A,B,C as above on cvs? Please show me the configuration on how to set it up. Many many thanks for your help.

I found that those space are removed on the project structure.
Here I discribe it again. BigProject have 3 sub-projects, Project_A, Project_B and Project_C. In Project_A, there are Prj_1, Prj_2 and Prj_3. In Project_B, there are Prj_4, Prj_5, Prj_6. In Project_C, there are Prj_7, Prj_8 and Prj_9.

Please help.
