Read only access to cvs

[Purushotham Komaravolu]

Hi,

     I am new to CVS administration.I need help in seting up the following.

1) Read only access to repository:

                                            Developers ger read/write access but QA and others get read-only access.

2) Multiple teams sharing different modules:

              We have multiple teams working on multiple modules.  Each teammember can access his/her teams module in RW(read/write) mode, where as he/she can access other team's module in read only fashion. PS:   is it recommended to have individual repositories for each project??

 

Can somebody advice me on how to setup/administer the following scenario in a manageable fashion.

Thanks

Regards,

Puru
