Delete a tag from a revision

[Disco Octopus]

Hi,

I would like to know how I can remove a tag from a revision.

Currently, when I do this...

cvs log do_the_great_stuff.java

I get this result...

I want to remove the V0309 from the revision 1.3

I tried this...
cvs tag -d V0903 do_the_great_stuff.java
... but it didn't work

Is this possible?

Thanks
