I never used this package myself and no longer want to maintain it. I might still fix bugs but all feature requests will be closed. Contact me if you are interested in becoming the new maintainer.
This package provides basic support for git svn, a Git command
that aims to provide bidirectional operation between a Subversion
repository and Git. See its manual page git-svn(1) for more
information.
When magit-svn-mode is turned on then the unpushed and unpulled
commit relative to the Subversion repository are displayed in the
status buffer, and N is bound to a popup with commands that wrap
the git svn subcommands fetch, rebase, dcommit, branch
and tag, as well as a few extras.
To enable the mode in a particular repository use:
cd /path/to/repository
git config --add magit.extension svn
To enable the mode for all repositories use:
git config --global --add magit.extension svn
To enable the mode globally without dropping to a shell:
(add-hook 'magit-mode-hook 'magit-svn-mode)
If you are looking for native SVN support in Emacs, then have a
look at psvn.el and info node (emacs)Version Control.
