     1.4 -"""
     1.5 - The goal of this module is to be a ctypes wrapper around the GEOS library
     1.6 - that will work on both *NIX and Windows systems.  Specifically, this uses
     1.7 - the GEOS C api.
     1.8 -
     1.9 - I have several motivations for doing this:
    1.10 -  (1) The GEOS SWIG wrapper is no longer maintained, and requires the
    1.11 -      installation of SWIG.
    1.12 -  (2) The PCL implementation is over 2K+ lines of C and would make
    1.13 -      PCL a requisite package for the GeoDjango application stack.
    1.14 -  (3) Windows and Mac compatibility becomes substantially easier, and does not
    1.15 -      require the additional compilation of PCL or GEOS and SWIG -- all that
    1.16 -      is needed is a Win32 or Mac compiled GEOS C library (dll or dylib)
    1.17 -      in a location that Python can read (e.g. 'C:\Python25').
    1.18 -
    1.19 - In summary, I wanted to wrap GEOS in a more maintainable and portable way using
    1.20 - only Python and the excellent ctypes library (now standard in Python 2.5).
    1.21 -
    1.22 - In the spirit of loose coupling, this library does not require Django or
    1.23 - GeoDjango.  Only the GEOS C library and ctypes are needed for the platform
    1.24 - of your choice.
