APRIL - Usage Instructions

Requirements

Besides a running Studierstube installation you need the following components for running APRIL presentations:

Setup

Install Saxon to a directory you like. Given that the java interpreter is in your path, you invoke the saxon translation of an APRIL file with the command

java -jar [saxon directory]/saxon.jar [path to presentation file] [april directory]/april_stb-3.0.xslt

you can of course put that into a batch file or shell script for convenient usage.

For windows machines, a batch script is provided to register the april file type for automatic expansion with the XSLT. Run the provided install-april.bat and enter the necessary information upon request. If you are using the Studierstube CD, the Studierstube installer should have taken care of that.

Note that for translating the presentations, you have to have the opentracker.dtd in the right location because of the referenced OpenTracker files being parsed by Saxon. Saxon will complain about missing DTDs and you can fix these problems by copying the correct DTD to the correct location.
