[cvsnt] Permission metadata?

[Anthony Lieuallen]

I've got an existing repository, and when it is checked out, certain 
files end up with unix permissions 600, but they need to be different 
than that.  I eventually found the "permissions     600;" line in the ,v 
file, but I can't find any proper way to alter that.  (I, of course, 
don't want to go editing the ,v file directly.)

So, what's the right command to run if I want to change the file that 
checks out as 600 to 660?
