I just used the instructions in this article by John Albin to archive an old svn project on my private machine.

A shell summary (see the John’s article for details):

svn log -q | awk -F '|' '/^r/ {sub("^ ", "", $2); sub(" $", "", $2); print $2" = "$2" <"$2">"}' | sort -u > authors-transform.txt
 
vim authors-transform.txt
# Make changes
 
git svn clone [SVN repo URL] --no-metadata -A authors-transform.txt --stdlayout ~/temp
 ~/temp
git svn show-ignore > .gitignore
git add .gitignore
git commit -m 'Convert svn:ignore properties to .gitignore.'
 
git init --bare ~/new-bare.git ~/new-bare.git
git symbolic-ref HEAD refs/heads/trunk
 ~/temp
git remote add bare ~/new-bare.git
git config remote.bare.push 'refs/remotes/*:refs/heads/*'
git push bare
 ~
rm -rf ~/temp
 ~/new-bare.git
git branch -m trunk master
 ~/new-bare.git
git for-each-ref --format='%(refname)' refs/heads/tags |
cut -d / -f 4 | ref
  git tag "$ref" "refs/heads/tags/$ref";
  git branch -D "tags/$ref";

John has also put all this into a number of scripts published on GitHub.
