How can I make a FREE Linux How-to PDF E-book available 
for download (to both Windows and Linux users) so that 
when someone clicks on a download button on an html 
web page, a PDF file would download (to either type 
of computer) with a progress bars showing the download 
status/progress and the result would be an icon on the 
desktop that one could click-on to open the PDF E-book?
