-It is easy to send Zulips on SVN commits, by configuring a post-commit hook. To do this:
-
-First, create the stream you’d like to use for SVN commit
-notifications, and subscribe all interested parties to this
-stream. The integration will use the default stream `commits` if no
-stream is supplied in the hook; you still need to create the stream
-even if you are using this default.
-
-Then:
-
-1. {! download-python-bindings.md !}
-2. Install `pysvn`. On Linux, you can install the `python-svn`
-package. On other platforms, you can install a binary or from source
-following the
-[instructions on the pysvn website](http://pysvn.tigris.org/project_downloads.html).
-3. Copy `integrations/svn/zulip_svn_config.py` and
-`integrations/svn/post-commit` from the API bindings directory to the
-`hooks` subdirectory of your SVN repository.
-4. Next, open `integrations/git/zulip_svn_config.py` in your favorite
-editor, and change the following lines to configure your SVN
-integration:
-
-        ZULIP_USER = "svn-bot@example.com"
-        ZULIP_API_KEY = "0123456789abcdef0123456789abcdef"
-        {% if api_site_required %}ZULIP_SITE = "{{ external_api_uri_subdomain }}"{% endif %}
-
-5. The default stream used by this post-commit hook is `commits`; if
-you’d prefer a different stream, change it now in
-`zulip_svn_config.py`. Make sure that everyone interested in getting
-these post-commit Zulips is subscribed to that stream!
