Committing changes to a Subversion repository

During the course of a project, plugin files will typically be created, modified, or deleted. These changes should be transmitted regularly to the Subversion repository to have proper backups of all the files in a project. A good practice is to commit changes at least once a day, with more frequent commit operations taking place when specific milestones are reached in the implementation of a plugin's features.

This recipe indicates how to manage file creation, modification, and deletion operations to keep everything organized and mirrored in the Subversion repository.

Getting ready

You should have already installed a Subversion client, created a local repository, and imported and checked out files before performing the steps in this recipe. These steps will be slightly different based on the Subversion client that you have selected and the operating system you are using.
