[cvsnt] file permission question

[Donny Y]

All,

I am trying to set permissions on a particular file via Windows
permissions.  I changed the permissions on the file in the repository such
that one user has read only access.  It succesfully denies access to that
one user.  The problem is that when a user with write permissions commit the
file, the permissions are blown away.  How can I get around this?  Thanks
for any help.
