cvs: how to put vendor-deleted file into Attic?

[Xin LI]

Hi,

While maintaining some third party contributed software packages I ran 
into a problem where, say, if I remove a file from the vendor branch 
(the file was never dragged off the vendor branch), it does not appear 
in Attic.

Is there a way to move it into Attic (presumably this would give better 
checkout speed for -HEAD)?

Cheers,
