svn log -r 1:HEAD --limit 1
{code}
h3. Example for two "easy" exports with no layout and (std-layout)
{code:sh}
git svn clone --trunk="https://svn.apache.org/repos/asf/turbine/site/" --authors-file=authors.txt --log-window-size=50000 -r223722:HEAD turbine-site
git svn clone --trunk="https://svn.apache.org/repos/asf/turbine/maven/turbine-parent/trunk/" --authors-file=authors.txt --log-window-size=50000 -r1199048:HEAD turbine-parent
{code}

Upload as below.

h3. Example for Init and Fetch in two steps with tags
h4. Init
{code:sh}
git svn init https://svn.apache.org/repos/asf/turbine/fulcrum/trunk/intake turbine-fulcrum-intake
{code}
Adapt turbine-fulcrum-intake/.git/config
{code:yaml}
[svn-remote "svn"]
   url = https://svn.apache.org/repos/asf/turbine/fulcrum
   fetch = trunk/intake:refs/remotes/trunk
   tags = tags/fulcrum-intake-*:refs/remotes/tags/*
{code}
h4. Fetch
{code:sh}
cd turbine-fulcrum-intake
git svn fetch -r222758:HEAD --ignore-paths="^branches" --log-window-size=50000 
{code}
h4. Update
{code:sh}
git remote add origin https://gitbox.apache.org/repos/asf/turbine-fulcrum-intake.git
git push -u origin master
{code}
h5. Update Tags
{code:sh}
$ git branch -a
* master
  remotes/origin/master
  remotes/tags/fulcrum-intake-1.1.0
  remotes/tags/fulcrum-intake-1.2.0
  remotes/tags/fulcrum-intake-1.2.1
  remotes/tags/fulcrum-intake-1.2.2
  remotes/tags/fulcrum-intake-1.2.3
  remotes/tags/fulcrum-intake-2.0.0
  remotes/trunk

$ for t in $(git for-each-ref --format='%(refname:short)' refs/remotes/tags); do git tag ${t/tags\//} $t && git branch -D -r $t; done
...

$ git branch -a
