Hi Andrew,

OpenSlide itself is a library, and does not include a graphical 
interface.  A polished GUI does not exist yet, but there are a couple 
demo programs that might be useful to you:

- The demo slide viewer in OpenSlide Java.  You can run this by 
executing the JAR.  You may encounter some visual glitches.

- The Deep Zoom server in OpenSlide Python.  You can get this by 
installing OpenSlide Python and running 
examples/deepzoom/deepzoom_server.py.  You can then view the slide with 
a web browser.

When configuring OpenSlide, you need to do something like:

./configure CPPFLAGS=-I/opt/openjpeg/include LDFLAGS=-L/opt/openjpeg/lib
