CVS admin -l DEPRECATED?

[Aditya Gandhi]

Hi all,
When I run the cvs -H admin command it shows that  the -l command has
been DEPRECIATED. This is on cvs client/ server
Client: Concurrent Versions System (CVSNT) 2.0.12 (client/server)
Server: Concurrent Versions System (scast-vc) (CVS) 1.11.1p1
(client/server)

While on 
Client: Concurrent Versions System (CVS) 1.11.9 (client)
Server: Concurrent Versions System (scast-vc) (CVS) 1.11.1p1
(client/server)

It does not mention that the command has been deprecated.

When was the command deprecated and do we know when it will be removed
from the available commands list?

Would this suggest that moving forward if we are rolling out a new
process for the team (we are using CVS for doc mgmt as well and
therefore need a way to lock docs) we should strongly advise them to use
cvs edit/ watch rather than cvs admin -l

Thanks and Regards
Aditya
