# Subversion

[Apache Subversion](https://subversion.apache.org/) is the version
control system that the 699 team uses. It plays a key role in our
software, file, and data management. For a quick tutorial on

## Installation for Macs 

There are two potential ways that you can use Subversion on Macs:

1.  The `svn` command line tool. Any instructions in this Wiki that
    require subversion will use this method.
2.  A GUI (Graphical User Interface) Client. Some GUI clients come with
    their own standalone svn version, but others may require you to also
    install the command line version.

The following steps pertain to method 1 (and method 2 if the GUI client
of your choice requires the command line version to be installed)

1.  Open up a new terminal window and execute `svn`
2.  If you already have `svn` installed then you will see the following
    message: `Type 'svn help' for usage.` Otherwise you should see the
    following dialog:\
    [500px](file:svn_install.png "wikilink")
3.  Go ahead and click \"Install\". You do not need to click \"Get
    Xcode\" since we are only interested in getting the command line
    tools. The download and installation may take a few minutes.
4.  Once the installation is finished you should see a dialog similar to
    the following:\
    <file:clt_install_done.png>
5.  Close your current terminal window and open a new one, then execute
    `svn` again. This time you should see `Type 'svn help' for usage.`.
    You now have Subversion installed!
