b_XYZ_descriptive

where <code>XYZ</code> are your initials and <code>descriptive</code> is a descriptive name for your branch.

'''Note''': Branches and branch tags are essentially ''immutable''. Once you make one, that branch is there.

==Branching files==

''Note'': With GEOS-5 we do not branch the entire model. Rather we branch individual files that are edited. There may be special circumstances when branching an entire directory (say, a leaf Gridded Component) might be correct, but this should only be done with approval.

To branch your modified file on a new branch, assume you've made modifications to file.F90 and want to save these to a new branch of the model. To do so:

Line 58:

cvs tag my-tag-name file.F90

cvs update -r my-tag-name file.F90

==Renaming tags==

With CVS it is fairly simple to rename a tag ''''that is not a branch tag'''''. Assume you have two tags, a <code>bad_tag</code> name you wish to change to a new <code>good_tag</code> name. First, tag all files that have the old tag with the new tag relative to that tag:

$ cvs tag -r bad_tag good_tag file1.F90 file2.F90 file3.F90

T file1.F90

T file2.F90

T file3.F90

Then remove <code>bad_tag</code> from those files:

$ cvs tag -d bad_tag file1.F90 file2.F90 file3.F90

D file1.F90

D file2.F90

D file3.F90
