+= Version Control with Subversion (svn) =
+== What is SVN? ==
+* A free/open-source version control system.
+* Managing files and directories over time, placed into a central repository.
+* The repository remembers every changes ever made to the files and directories.

+
+== Good things... ==
+* If you develop a software with some other people, it keeps track of who did what when and where changes.
+  * even if you develop a software yourself...
+* When you made a stupid change and screwed up ....
+  *Allows you to go back.
+  *Revert to a previous revision of a file/directory.
+

+
+== First things to do ==
+* Create a repository on sphynx
+{{{
+svnadmin create $HOME/repos
+}}}
+This creates a repository under '$HOME/repos'.
+
+Note that $HOME is your home-directory on sphynx.
+
+Once you did this, you don't have to do this again. Do not delete '$HOME/repos' !!!
+  * Testing your repository
+On sphynx,
+{{{
+mkdir mywork
+cd mywork
+mkdir project1
+echo "This is README.txt" > README.txt 
+svn import file:///$HOME/repos/project1 -m"initial import"
+}}}
+Now you have ''project1'' in your repository.
+
+Delete ''project1'' then checkout project1 from the repository,
+{{{
+cd ..
+rm -rf project1
+svn co file:///$HOME/repos/project1 ./project1
+}}}
+
+== Working with SVN ==
+* To download files in a repository, use 'svn checkout' / 'svn co' command.
+* If you made some changes to the files in your local machine and want to upload these to the repository, use 'svn commit' command.
+* If you have files on your local machine and want to update these to the latest version in the repository, use 'svn update' command.
+* If you want to add a file/direcotry, use 'svn add' and commit.
+* If you want to delete a file/directory, use 'svn delete' and commit.
+
+== What to Control ==
+* Source Code
+* Documents
+* Variable data
+* Anything you want to share that isn't essentially static data.
+
+'''Do not upload.... Large sets of binary files; images, movie, music....'''
+
+== Accessing your Repository over Network ==
+To access your Repository on sphynx' through ssh from other hosts,
+
+{{{
+svn co svn+ssh://USERNAME@sphynx.ccs.tulane.edu/HOME_DIRCTORY/repos/project1 ./project1
+}}}
+
+You will be asked for typing your password on sphynx.
+
+USERNAME and HOME_DIRCTORY are your login user name and home directory on sphynx.
+
+To see the path of your home directory, on sphynx
+{{{
+cat $HOME
+}}}
+* Using svn-client software with GUI
+  * There are Windows Versions and Mac OS versions.
