Subject: [PATCH] Add a new makefile for the third-party libraries. Change the
 'lib' target in the main makefile to recurse into the 'lib' directory. Add
 'lp_solve' and 'lp_solve_55' directories to the library .gitignore. Update
 the readme with new instructions.

-Third-party libraries are stored here. Currently, Shapely is the only
-one we're using which isn't available through package managers.
+Third-party libraries are stored here. Currently, we use Shapely and
+lp_solve (along with its Python bindings). To install them, simply run
+'make' within this directory. You can also run 'make lib' in the
+top-level directory.
 
-Shapely should be downloaded and extracted:
-
-  wget http://pypi.python.org/packages/source/S/Shapely/Shapely-1.0.14.tar.gz
-  tar -xvzf Shapely-1.0.14.tar.gz
-  mv Shapely-1.0.14 Shapely
-  rm Shapely-1.0.14.tar.gz
-  
-This will probably be handled by the makefile.
+You will need GEOS installed for Shapely to work properly.
