Subversion (commonly referred to as '''SVN''') is a source-code control system. It can keep track of files, their history over time, and when different users change them. It's designed to keep track of data to answer questions like:

* When was this section added?
* Who made modification X?
* What did this file look like when I used it 3 months ago?

	===Using SVN from the command line (Linux or cygwin)===		===Using SVN from the command line (Linux or cygwin)===
		+	Using ssh-agent is highly recommended to avoid annoying password prompts all the time while still keeping the server relatively secure.
		+
		+	====One-time setup====
		+	On each client, create a password-protected ssh key:
		+	oborn@winnebago:~$ ssh-keygen -t rsa
		+	Generating public/private rsa key pair.
		+	Enter file in which to save the key (/home/oborn/.ssh/id_rsa):
		+	Created directory '/home/oborn/.ssh'.
		+	Enter passphrase (empty for no passphrase):
		+	Enter same passphrase again:
		+	Your identification has been saved in /home/oborn/.ssh/id_rsa.
		+	Your public key has been saved in /home/oborn/.ssh/id_rsa.pub.
		+	The key fingerprint is:
		+	0d:77:74:1c:3d:c5:45:ba:1c:05:88:1e:af:c8:b0:79 oborn@winnebago
		+	The key's randomart image is:
		+
		+	Make sure to enter a password '''different from your server password''' for the password fields. Next copy the key to devsource.
		+
		+	oborn@winnebago:~/.ssh$ scp ./id_rsa.pub oborn@134.50.3.139:.ssh/client.pub
		+	oborn@134.50.3.139's password:
		+	id_rsa.pub
		+
		+	SSH into devsource and append the key to authorized_keys:
		+
		+	oborn@winnebago:~/.ssh$ ssh 134.50.3.139
		+	oborn@134.50.3.139's password:
		+	Linux devsource 2.6.32-24-server #43-Ubuntu SMP Thu Sep 16 16:05:42 UTC 2010 x86_64 GNU/Linux
		+	Ubuntu 10.04.1 LTS
		+	Last login: Tue Sep 28 01:39:22 2010
		+	oborn@devsource:~$ cd .ssh/
		+	oborn@devsource:~/.ssh$ cat client.pub >> authorized_keys
		+	oborn@devsource:~/.ssh$ exit
		+	logout
		+	Connection to 134.50.3.139 closed.
		+
		+	====Setup for each client console that you will use svn in====
		+
		+	Start ssh-agent:
		+
		+	oborn@winnebago:~$ eval `ssh-agent`
		+	Agent pid 28009
		+
		+	Add the ssh-key to ssh-agent:
		+	oborn@winnebago:~$ ssh-add ~/.ssh/id_rsa
		+	Enter passphrase for /home/oborn/.ssh/id_rsa:
		+	Identity added: /home/oborn/.ssh/id_rsa (/home/oborn/.ssh/id_rsa)
		+	Enter the password you used when creating the key, not the password for the server.
		+
		+	And test the ssh connection:
		+	oborn@winnebago:~$ ssh 134.50.3.139 hostname --long
		+	devsource.iac.isu.edu
		+	This should '''not''' prompt for a password (ssh-agent and your key will provide security).
		+
		+
		+	===SVN commands===
		+	The basic structure of the URL for repository access is:
		+	svn+ssh://user@server/path/
		+
		+	For example, to log in as "brian" on devsource.iac.isu.edu and access the homework directory:
		+	svn+ssh://brian@devsource.iac.isu.edu/home/brian/svn/homework/407/
		+
		+	The svn list command lists the files in a repository:
		+	svn list svn+ssh://brian@134.50.3.139/home/brian/svn/homework/407/
		+	406_template.pdf
		+	406_template.tex
		+	407_HW1.pdf
		+	407_HW1.tex
		+	407_HW1_soln.pdf
		+	407_HW1_soln.tex
		+	407_HW2.pdf
		+	407_HW2.tex
		+	407_HW3.pdf
		+	407_HW3.tex
		+	mod_1.2.cpp
		+	mod_1.3.cpp
		+	mod_1.4.cpp
		+	mod_1.5.cpp
