About the test data
The fountain website has some good files for reviewing formatting difference between fountain, fdx and PDF. Some are referenced in the test programs but they are optional. It is not clear to me the licensing arrangements for the text so I have not included them in this repository.
If you want to include them in the test sequence go to the fountain
website and download them and place them in the testdata
directory. When you run go test they will be found and
included in the basic test process.
