+Implementing User-Defined Functions
+===================================
+
+:Author: Sjoerd Mullender
+:Organization: CWI, MonetDB B.V.
+:Abstract: In this short tutorial we describe how to create a simple
+   UDF for MonetDB/SQL.
+
+Introduction
+------------
+
+In this directory there are a number of tutorials for creating
+user-defined functions.  It is recommended to go through these
+tutorials in the order presented here, since they will go from simple
+to more complicated.
+
+Setting Up
+----------
+
+These tutorials work completely outside the source of the MonetDB
+suite.  You do not need to copy the source of MonetDB, and you do not
+need to recompile the MonetDB sources.  You do need to install some
+extra packages that are not normally installed.
+
+On Fedora and RedHat-based systems you need to install the packages
+``MonetDB5-server-devel``, ``MonetDB-devel``, and
+``MonetDB-stream-devel``.  On Debian and Ubuntu you need to install
+the packages ``monetdb5-server-dev``, ``libmonetdb-dev``, and
+``libmonetdb-stream-dev``.
+
+Tutorials
+---------
+
+reverse
+.......
+
+Start with the tutorial in the ``reverse`` subdirectory.  In this
+tutorial you will create a simple user-defined function (UDF) that
+takes one (string) value as input and produces one (string) value as
+output.
