Hi all,
As you should know, when developing an application, it is extremely important to keep track of the different versions and updates that we come up with. At some point, we might want to take a different approach and do a new branch of our code, we could be considering trying new features or any fancy new things. With version control softwares we can do this and still keep our main thread of the code, the trunk. These kind of software also provide great capabilities for teamworking. Another great feature these softwares have, is the possibility to close a version. Sometimes in app developing, you might have to hand in a deliverable during the process of development, that is why tags exist. They close a version, and provide the possiblity to come back and start developing from that checkpoint.

 Possible scenario for an app lifecycle

I usually use Eclipse for application programming, depending on the platform obviously, and there are two possiblities for using the Subversion (version control software) in this IDE: Subclipse or Subversive. The one I decided to use? Subversive, which is developed and supported by the eclipse team. Now I´m going to try to explain how to fork a project and start developing and looking around different folders.
After Subversive is installed, we should open a new perspective window in our Eclipse in order to be able to browse through our repository. To open the perspective: Window > Open Perspective > Other and we look for the SVN Repository Exploring.
In that perspective, we have two main options: Create a new repository, or set a new location where we already have a repository. We would have to fill in a couple of settings, and we should see the repository in that view.
Now, to start working or checking code from the project, we must download it to our computer. To do so, we check the trunk or brunch we want to download, right-click with the mouse, and select Check-out. Then we will have the project in our projects view.
