Overview
************************************************************************
In this example, we show how to use callbacks on metadata by extracting 
a GIF file from an HTTP response.
Metadata used are:
- HTTP MIME type: check if MIME type is "image/gif"
- HTTP Content: to feed the GIF file

************************************************************************
Installation
************************************************************************
make: build application
make install: install application in src/bin directory

Notes:
build is dynamic by default.
Set STATIC=1 for static build.
Set DEBUG=1 to get debug info.

************************************************************************
Usage
************************************************************************
./attribute_extraction <pcap_file>

A pcap file is included for quick testing:
http_get_gif_file_workflow.pcap

The LD_LIBRARY_PATH variable can be set as follows from this directory:
$ export LD_LIBRARY_PATH=../../../lib
