Building:
Open the Xcode workspace Analyser.xcworkspace and hit Cmd-B to build.
There is a library part "LibAnalyser" and a front-end part, "AnalyserFE".
Locate the built executable by selecting Project Navigator > AnalyserFE > Products > AnalyserFE then right clicking and 'Show in Finder'.
Drop a test file into that directory. Call it 'infile'.
Running:
Run the Analyser with Cmd-R. It will pick up 'infile' and output a new file as 'outfile'.
That's it!
