+MongoDB Haskell Mini Tutorial
+-----------------------------
+
+  __Author:__ Brian Gianforcaro (b.gianfo@gmail.com)
+
+  __Updated:__ 2/28/2010
+
+This is a mini tutorial to get you up and going with the basics
+of the Haskell mongoDB drivers. It is modeled after the python tutorial
+pymongo available here: http://api.mongodb.org/python/1.4%2B/tutorial.html
+
+You will need the mongoDB bindings installed as well as mongo itself installed.
+
+>$ = command line prompt
+> = ghci repl prompt
+
+
+Installing Haskell Bindings
+---------------------------
+
+From Source:
+ 
+> $ git clone git://github.com/srp/mongoDB.git
+
+> $ cd mongoDB
+
+> $ runhaskell Setup.hs configure
+
+> $ runhaskell Setup.hs build
+
+> $ runhaskell Setup.hs install
+
+From Hackage using cabal:
+
+> $ cabal install mongoDB
+
+
+Getting Ready
+-------------
+
+Start a MongoDB instance for us to play with:
+
+> $ mongod
+
+Start up a haskell repl:
+
+> $ ghci 
+
+Now We'll need to bring in the MongoDB/BSON bindings:
+
+> import Database.MongoDB
+
+> import Database.MongoDB.BSON
+
+Making A Connection 
+-------------------
+Open up a connection to your DB instance, using the standard port:
+
+> con <- connect "127.0.0.1" 
+
+or for a non-standard port
+
+> import Network 
+> con <- connectOnPort "127.0.0.1" (Network.PortNumber 666)
+
+Getting the Databases
+------------------
+
+> dbs <- databaseNames con
+> let testdb = head dbs
+ 
+
+Getting the Collections
+-----------------------
+
+> collections <- collectionNames con testdb
+> let testcol = head collections
+
+Documents
+---------
+
+BSON representation in Haskell
+
+Inserting a Document
+-------------------
+
+> insert con testcol (toBsonDoc [("author", toBson "Mike"), ("text", toBson "My first Blog post!"), ("tags", toBson ["mongodb", "python","pymongo"])]) 
+
+
+Getting a single document with findOne
+-------------------------------------
+
+> findOne con curcol (toBsonDoc [("author", toBson "Mike")])
+
+Querying for More Than One Document
+------------------------------------
+
+> cursor <- find con curcol (toBsonDoc [("author", toBson "Mike")])
+
+> allDocs cursor
+
+ See nextDoc to modify cursor incrementally one at a time. 
+
+ * Note: allDocs automatically closes the cursor when done, through nextDoc.
+
+
+Counting
+--------
+
+  We can count how many documents are in an entire collection:
+
+> num <- count con testcol
+
+  Or we can query for how many documents match a query:
+
+> num <- countMatching con  testcol (toBsonDoc [("author", toBson "Mike")])
+
+Range Queries
+-------------
+
+  No non native sorting yet.
+
+Indexing
+--------
+
+ WIP - coming soon.
+
+ Something like...
+> index <- createIndex con testcol [("author", Ascending)] True
