 Lambert Azimuthal Equal Area
 ============================
 
+This projection was developed by Johann Heinrich Lambert in 1772 and is typically used
+for mapping large regions like continents and hemispheres. It is an azimuthal,
+equal-area projection, but is not perspective. Distortion is zero at the center of the
+projection, and increases radially away from this point.

 ``Alon0/lat0[/horizon]/width``: ``lon0`` and ``lat0`` specifies the projection center.
 ``horizon`` specifies the max distance from projection center (in degrees, <= 180,
 default 90).
