The qpdf-wrapper-class.zip file contains qpdf.pas, a Delphi class
called "TQPDF" that wraps around qpdf by making calls to qpdf.dll
using the export "C"-language API.
The qpdf-demo-application.zip file contains additional sources to
build a PDF linearization (also known as "fast web view") application
that uses TQPDF behind the scenes to do the PDF work.
These files are released under version 2.0 of the artistic license,
the same as qpdf itself.
