+All source, data files and other contents of the PROJ.4 package are 
+available under the following terms.  Note that the PROJ 4.3 and earlier
+was "public domain" as is common with US government work, but apparently
+this is not a well defined legal term in many countries.  I am placing 
+everything under the following MIT style license because I believe it is
+effectively the same as public domain, allowing anyone to use the code as
+they wish, including making proprietary derivatives. 
+
+Though I have put my own name as copyright holder, I don't mean to imply
+I did the work.  Essentially all work was done by Gerald Evenden.
