repository - How to generate log in cvs containing the diffrence of revision -

I am using the CVS repository and I am using CVS difference, but only in the difference can I see the modified file I am, but I want to know who made these changes.

So I want the author's name and the difference, which changes the same log file in this modification.

Is there any such order available in the CVS?

If you are looking for authoring information (file is created) < Previous> CVS log & lt; Filename & gt;

This will give you every correction, author, added lines, etc.
