If you want to import a local subversion repository (maybe a dump) to git you can do this quite easily:
First you need to map the Subversion commit authors to Git commiters. For you just create a textfile author-mapping.txt:
And then you run the following commands:
mkdir repo && cd repo git svn init file:///path/svnrepo --no-metadata git config svn.authorsfile ~/author-mapping.txt git svn fetch
Sometimes the protocol file:// cannot be handled. In that case you can run svnserve –daemon to serve your subversion repository locally. Then you can use svn://localhost/svnrepo instead.
