"import" meet "\" problem

cvs -d:pserver:name@cvs.tigris.org:/cvs import learndiary\old learndiary initial

error message says I have no write access to cvs authority.

But,I own the write authority to cvs.

Later,change "\" into "/",like below:

cvs -d:pserver:name@cvs.tigris.org:/cvs import learndiary/old learndiary initial

That's ok.
