How can I create a branch from a existing branch in cvs

I have one branch nam开发者_Go百科ed "Gem36" but I want to create another branch named "RM_Gem36" from the existing branch. How can I do that in CVS?

Is there any other way to create new branch "RM_Gem36"from existing branch without checking out the "Gem36" branch?

You can checkout Gem36 and create new branch with the following command:

$ cvs tag -b RM_Gem36

Or you can try to do this without checking out:

$ cvs rtag -b -r Gem36 -- RM_Gem36 "module_name"
