+==============
+
+Use a PostgreSQL result cursor from node with an easy to use API.
+
+### install
+
+```sh
+$ npm install pg-cursor
+```
+___note___: this depends on _either_ `npm install pg` or `npm install pg.js`, but you __must__ be using the pure JavaScript client.  This will __not work__ with the native bindings.
