For commits to the CESM svn repo

1. check out the latest cesm tag but do not populate external directories

svn co --ignore-externals $SVNREPO/cesm1/tags/cesm1_3_alpha## my_sandbox svn co -N $SVNREPO/cesm1/tags/cesm1_3_alpha## my_sandbox

2. modify the file SVN_EXTERNAL_DIRECTORIES with any changes to component tags

cd my_sandbox emacs SVN_EXTERNAL_DIRECTORIES

3. set the property for the external definitions - don't forget the dot at the end

svn propset svn:externals -F SVN_EXTERNAL_DIRECTORIES .

4. populate your sandbox with the external files

svn update

5. test

6. document your mods

cp ChangeLog_template ChangeLog.new cat ChangeLog >> ChangeLog.new emacs ChangeLog.new mv ChangeLog.new ChangeLog

7. copy your sandbox to a new tag in the repository

svn copy . $SVNREPO/cesm1/tags/cesm1_3_alpha## -m "created tag cesm1_3_alpha##"
