Wrappers for the Proj.4 library. A copy of this package exists also in the jniwrap directory of the Proj.4 project. This GeoAPI package differs from the Proj.4 package in the following (note that this is a compatible difference):
org.opengis.wrapper.proj4package. It should generally not be used directly, unless an implementor wants more direct access to the Proj.4 functions.
