--  > lon0 = 22.350 * pi / 180 -- Test longitude in radians.
--  > lat0 = 40.084 * pi / 180 -- Test latitude in radians.

Description:
  Haskell bindings for the Proj.4 map projection C library.
  .
  You need to have Proj.4 already installed as a shared library.
  .
  Example transformations (from <http://www.mysqludf.org/lib_mysqludf_fPROJ4/>):
  .
  > import Geo.Proj4
  > 
  > lon0 = 22.350 * pi / 180 -- Test longitude in radians.
  > lat0 = 40.084 * pi / 180 -- Test latitude in radians.
  > alt0 = 2843 -- Test altitude in meters.
  > 
  > -- | Test projection:
  > pj = newProjection "+proj=utm +zone=34"
  > 
  > -- | Another test (null, e.g. cylindrical) projction:
  > pj0 = newProjection "+proj=latlong +ellps=clrk66"
  > 
  > -- | A projection of our test longitude & latitude, using @pj:
  > (x, y) = pjFwd pj (lon0, lat0)
  >

  > main :: IO ()
  > main = do
  >     putStrLn $ "(x, y): " ++ (show (x, y))
  >     putStrLn $ "(lon, lat): " ++ (show (lon * 180 / pi, lat * 180 / pi))
  >     putStrLn $ "(x, y, z): " ++ (show $ (x2, y2, z2))
  >     return ()
