# Feature Showcase: Using Source Code Control

Komodo has integration features for CVS, Perforce, and Subversion. This feature showcase uses Subversion as the example.

Open the Preferences to check the Subversion configuration. If the svn executable is in your PATH, you should not have to change anything.
You can right click on a file in a project for a context menu with some common SCC commands...
... or use the buttons in the SCC toolbar.
The History button will show a list of file revisions.
Clicking "Diff with local copy" in the History dialog box will show the differences between the selected revision and the current local copy. Clicking the Diff button will show the differences between the file in the current editor tab and the last revision.
The output of all SCC commands is shown in the Output tab in the bottom pane.
