This is the official Perforce plugin that is shipped with Unity, as a built-in Version Control provider.
On Windows it is shipped as Editor\Data\Tools\VersionControl\PerforcePlugin.exe.
See also the Community Supported Perforce (Helix Core) plugin for Unity It is a fork of these code, but allows the linked version of the P4 API to be changed as needed, and provide more recent builds.
You can build support for you own favorite version control system into Unity by cloning this repository and make changes as needed.
A plugin is an executable located in a designated directory that Unity can start and kill at will. At startup, Unity will scan the directory and start each executable in order to identify the plugin and its settings. When a version control system has been enabled in unity it will start the associated plugin executable and send commands to it by using stdin/stdout (MacOS) or Named Pipes (Windows).
The Perforce plugin is using the libraries provided by Perforce and its callback style API. Furthermore, is streams results from the perforce server directly to Unity.
You need Unity 4.2+ to use the integrated version control plugins.
