19-Mar-99: Version 2.0
	   - Support plotutils 2.2 API enhancements.
           - Put the whole binding under the GNU package hierarchy.
	   - Rearrange the widget set dependencies. The binding itself now
	     doesn't depend on the widget set used to build the plotutil
             package. For your conveniance there are packages that just
	     contain the Linker_Options pragmata required to link an
	     application using this binding for a given widget set.

17-Oct-98: Version 1.6 (non public)
	   - eliminate the device-specific packages in favour of the
	     generic ones.

12-Oct-98: Version 1.5
	   - Support of new AI device in plotutil-2.1.5
	   - Change the way how new Drivers are incorporated
	     to a generic mechanism, so I don't have to update
	     the binding when a new driver type comes up.

28-Aug-98: Version 1.4
	   - Support of new PCL device in plotutil-2.1.5

20-Jun-98: Version 1.3
	   - Some support to automatically configure the required
	     libraries in the Linker_Options

24-Apr-98: Version 1.2
	   - Enhanced to support the new version 2.1 of plotutils.
	     There is a new function to set the background color
	     for 'X' and 'X Drawable' Plotters.

09-Apr-98: Version 1.1
           - Added plotting in the Complex plane
           - Improve binding by using 'Base attribute for angles,
	     radiuses and sizes. They typically represent an amount that
             not necessarily fits into the coordinate system.
