User Defined Functions

Several external computation systems support the concept of a User Defined Function (UDF). A UDF is simply a way of making functionality (in this case the analysis of useragents) available in such a system.

For several systems (tools used within bol.com (where I work)) I have written such a UDF which are all part of this project.
