How do I migrate an SVN repository with history to a new Git repository?

Question

I read the Git manual, FAQ, Git - SVN crash course, etc. and they all explain this and that, but nowhere can you find a simple instruction like:

Cleanly Migrate Your Subversion Repository To a Git Repository. First you have to create a file that maps your Subversion commit author names to Git commiters, say ~/authors.txt:

jmaddox = Jon Maddox 
bigpappa = Brian Biggs 

Then you can download the Subversion data into a Git repository:

mkdir repo && cd repo
git svn init http://subversion/repo --no-metadata
git config svn.authorsfile ~/authors.txt
git svn fetch

If you’re on a Mac, you can get git-svn from MacPorts by installing git-core +svn.

If your subversion repository is on the same machine as your desired git repository, then you can use this syntax for the init step, otherwise all the same:

git svn init file:///home/user/repoName --no-metadata
