Change to the directory containing the code you want to brach from (ex. use
cvs co -r [tagname] to branch old tagged code).
Now you can add the branch by issuing the following command:
cvs tag -b [new branchname]
Finish changes to the working directory, then
Example branching at revision tag
cvs -d /mnt/data/CVSHOME co -r R0_3_3 miav cd miav cvs tag -b stable_0_3 # do some changes in the code cvs commit -m"Made a change in a branch"
