     NDPluginDriver is the class from which actual plugins are directly derived. The
     NDPluginDriver class handles most of the details of processing NDArray callbacks
     from the driver. Plugins derived from this class typically need to implement the
-    processCallbacks method, the drvUser method, and one or more of the write(Int32,
-    Float64, Octet) methods. The <a href="areaDetectorDoxygenHTML/class_n_d_plugin_driver.html">

     NDPluginDriver defines parameters that all plugin drivers should implement if possible.
-    These parameters are defined by enum values with an associated asyn interface, and
-    access (read-only or read-write). The EPICS database NDPluginBase.template provides
-    access to these standard plugin parameters, listed in the following table. Note
-    that to reduce the width of this table the enum names have been split into 2 lines,
