Windows PDF view helper
Author: Joost Verburg
This will be installed as pdfview.exe.
The application will launch the default PDF viewer to display the PDF file,
but works around the file locking problems of Adobe Reader.
Source code of pdfopen/pdfclose is available at:
http://magic.aladdin.cs.cmu.edu/2005/07/15/pdfopen-and-pdfclose/
