What is Subversion?
Subversion is a control system version free / open-source. That is, Subversion manages files and directories, and the changes made to them over time. This allows you to recover older versions of your data, or examine the history of their changes. Because of this, many people think of a version control system as a sort of “time machine”.
Subversion can operate across networks, which allows it to be used by people on different computers. On one level, the ability for various people to modify and manage the same set of data from their respective locations fosters collaboration. Progress can occur more quickly without a single conduit through which all modifications must occur. And because the work is versioned, you need not fear that their work quality for not miss this one for changes via the data suffers an improper modification, just undo that change.
