The proj package supplies a cartographic projection library and
utilities. It is based on the 'Proj.4' distribution at
http://trac.osgeo.org/proj/, not the friendly 'libproj4' fork
at http://members.verizon.net/~gerald.evenden/proj4/.

This is a routine update.

[[ compiled using gcc-3.4.4-999 ]]

This is the first release specific for cygwin-1.7; the only differences
between this package and the simultaneously-released proj-4.6.1a-1 for
cygwin-1.5 are documentation related (the README references cygport-0.9.5
and cygwin-1.7.0-43, and the /usr/share/doc/ layout is influenced by the
cygport changes between 0.4.x and 0.9.x).

CHANGES (since 4.5.0a-1)
o Fork for cygwin-1.7 development
o Update to latest upstream release (actually, svn as of 20090311)
o Update to work with stock cygport-0.9.5
o Version bump: new libproj1 package supplies cygproj-1.dll.
  Older libproj0 package now in _obsolete state, but still
  available via the libproj0-4.5.0a-1 package.
o Added pkgconfig file
o Added additional documentation
o geod functions removed from the library (this required the
  DLL version bump).  These were originally added by the
  cygwin-custom release 4.5.0a-1 in 2007. Back then, it looked
  likely that these functions would eventually be added upstream,
  but they haven't and it is now clear that they won't be, due
  to issues with the coding style, disagreement over the
  algorithm, and the new availability of libgeodesic:
o Also, upstream removed the mpoly projection. Since it
  was an unused dummy projection (no actual transformation),
  they figured it didn't count as breaking the ABI...
o In 4.6.0 code was added to handle windows drive letters,
  thus eliminating the need for some of our older patches.
