A presenter console with multi-monitor support for PDF files.

pdfpc is a GTK based presentation viewer application which uses
Keynote like multi-monitor output to provide meta information to
the speaker during the presentation. It is able to show a normal
presentation window on one screen, while showing a more sophisticated
overview on the other one providing information like a picture of
the next slide, as well as the left over time till the end of the
presentation. The input files processed by pdfpc are PDF documents,
which can be created using nearly any of today's presentation
software.

More information, including screenshots and a demo presentation, can
