Changing the CVS keywork substitution mode

If you want to change the CVS keywork substitution mode, you unfortunately cannot do it with NetBeans, but you can use this few steps:
- let's say the new keyword substitution mode should be -kkv
- cvs admin -kkv File.java
- cvs update -kkv File.java
- edit the File.java to change it a bit
- cvs commit -fm "Change substitution mode" File.java

I've used this on number of files, so it does work.
