This doc explains how to create/work/re-merge svn branches

#######################################
### make a new branch               ###
#######################################

we will create a branch clone-skip-unstable

tag before the branch:

  svn copy https://svn.apache.org/repos/asf/perl/modperl/trunk \
    https://svn.apache.org/repos/asf/perl/modperl/tags/pre-clone-skip \
    -m "tag before branching for CLONE_SKIP support"

branch:

  svn copy https://svn.apache.org/repos/asf/perl/modperl/trunk \
    https://svn.apache.org/repos/asf/perl/modperl/branches/clone-skip-unstable \
    -m "branching to provide CLONE_SKIP support"

check out:

  svn co https://svn.apache.org/repos/asf/perl/modperl/branches/clone-skip-unstable mp2-clone-skip-unstable

change externals to point to the new A-T branch (if one was done)

  svn propedit svn:externals .

#######################################
### sync the branch with the trunk  ###
#######################################

the branch was created @r165203

  svn co https://svn.apache.org/repos/asf/perl/modperl/branches/clone-skip-unstable \
         mp2-clone-skip-unstable
  cd mp2-clone-skip-unstable
  svn propset merge-point 165203 .
  build/svn.remerge

now resolve any conflicts and commit the changes


#######################################
### merge the branch into the trunk ###
