Locking CVS

[S I]

Hi everyone,

I'm planning to lock cvs today getting ready for our release.  I realize 
with certain version control software nowadays you don't have to lock the 
repo and the developers can continue with their work.  However, we're 
imposing and enforcing a few days for freeze and to regroup.

Our repository resides on a linux box with :pserver method access from WinXP 
CVS DOS and Tortoise clients.  Could I just lock the repo by executing cvs 
admin -l or -L  or do I have to download some perl module to accomplish 
this? I need to lock our CVS repository today.  Three projects reside in the 
repository, is it possible to lock them selectively or would admin -l lock 
the entire repo?

Thanks
steven
