+point_to_point_routing
+======================
+
+This repository have library for point to point routing. 
+
+
+Prerequisites
+-------------
+
+1.	Install PostgreSQL - version 9.1
+
+2.	Install PostGIS - version 1.5
+
+3.	Install Pgrouting - version 1.05

+
+sql file available here. 
+
+
+Attributes Requirement in the routable table are as below:
+-----------------------------------------------------------
+1. start_id
+
+2. end_id
+
+3. the_geom
+
+4. osm_name
+
+5. speed_in_kmh
+
+6. length
