QGIS aims to be an easy to use GIS, providing common functions and
features. The initial goal was to provide a GIS data viewer. QGIS has
reached that point in its evolution and is being used by many for their
daily GIS data viewing and editing needs. QGIS supports a number of raster
and vector data formats, with new support easily added using the plugin
architecture.

This package tracks the 4.0 stable branch.  NB: 4.0 is labeled "Very
Early Adopter.  It uses qt6. Some plugins are unavailable, and more or
less everything isn't adequately well tested yet.
