The problem of source control occurs when you don’t have any management software. If you have a central location for data and two people are using the same storage, such as the same file, the second person to save a file can overwrite the first person’s changes. Source control software can prevent this, by either capturing both sets of changes and merging them together, or by preventing two people from having the same file checked out at the same time.
CVS is designed to allow developers to work simultaneously on a file. Several people can work on the same file, each in their own sandbox, and CVS tries to merge their changes to the data in the central repository. If the changes can’t be merged easily, the developer who commits the second set of changes is asked to resolve the conflict. This pattern is explained in Chapter 3.
An alternative to simultaneous development is exclusive development, where one developer at a time has the editing rights for a file.
