The main purpose of this gadget is displaying the data distribution among
various sources, like shares, disk capacity and free space, etc. on a graphical
pie chart. Optionally interaction from the user is also possible.

Features of the class:

* Dynamic handling of slice lists

* Multiple level of slices, to display hierarchical data

* Automatic calculation of sizes for given slice values, summary child slice
values to set the parent value

* Various properties for appearance of the whole chart and the slices

* Support for layout.gadget/window.class backfills

* Support for identifying user clicks on slices

What is needed for development of a software, which makes use of the gadget is
included in this package: all C headers, Autodoc, examples with sources.

Changes since 52.2:

- FIX: calculated slice values were wrong when the sum of child values
  exceeded 2^32-1. (Thanks to Alexander Weber for reporting the error.)
