Lele Gaifax wrote a nice utility called `Tailor <Tailor>`_ to
convert between all sorts of repositories. Here is a recipe for
importing your subversion repository into darcs and maintaining a
two-way sync:

'**'WARNING**: The process described here may lead to problems. See
`http://www.mail-archive.com/tailor@lists.zooko.com/msg00080.html <http://www.mail-archive.com/tailor@lists.zooko.com/msg00080.html>`_
. Apparently a safe (but more complex) method is outlined at
`http://progetti.arstecnica.it/tailor/wiki/TwoWaySync.'' <http://progetti.arstecnica.it/tailor/wiki/TwoWaySync.''>`_

The configuration file
~~~~~~~~~~~~~~~~~~~~~~

Save the following in ``/whatever/myNiftyProject.tailor``:

::

    [DEFAULT]
    verbose = True
    projects = darcs-to-svn
    
    [darcs-to-svn]
    root-directory = /tmp
    source = darcs:myNiftyProject
    target = svn:myNiftyProject
    state-file = darcs-to-svn.state
    
    [svn-to-darcs]
    root-directory = /tmp
    source = svn:myNiftyProject
    target = darcs:myNiftyProject
    state-file = svn-to-darcs.state
        
    [svn:myNiftyProject]
    repository = http://myWonderfulServer.org/myNiftyProject
    module = /trunk/myNiftyProject
    subdir = svnside
    
    [darcs:myNiftyProject]
    repository = /whatever/myNiftyProjectInDarcs
    subdir = darcside

Making it go
~~~~~~~~~~~~

Now, how do you make this work?

By saving the file somewhere, such as
``/whatever/myNiftyProject.tailor``. Then you can run it as
follows:

-  ::

       cd

   into the directory where you put tailor.
-  Then, run this:
   ``./tailor --configfile=/whatever/myNiftyProject.tailor svn-to-darcs
``

This will give you a nice darcsified version of your repository in
``/tmp/darcside``(or whatever ``root-directory``and ``subdir``you
set in the configuration file).

Saving things back in SVN
~~~~~~~~~~~~~~~~~~~~~~~~~

*WARNING: This is not tested, however it should work...*

Not everyone's on board that darcs is the way to go? No problem:

-  ::

       cd

   into the directory where you put tailor.
-  Then, run this:
   ``tailor --configfile=/whatever/myNiftyProject.tailor darcs-to-svn
``

The SVN version of your repository will now be at
``/tmp/svnside``.
