<brief_description>
Version Control System (VCS) interface, which reads and writes to the local VCS in use.
</brief_description>
<description>
Defines the API that the editor uses to extract information from the underlying VCS. The implementation of this API is included in VCS plugins, which are GDExtension plugins that inherit [EditorVCSInterface] and are attached (on demand) to the singleton instance of [EditorVCSInterface]. Instead of performing the task themselves, all the virtual functions listed below are calling the internally overridden functions in the VCS plugins to provide a plug-n-play experience. A custom VCS plugin is supposed to inherit from [EditorVCSInterface] and override each of these virtual functions.
