# The ebook-viewer utility of the Calibre project MODIFIES ANY EPUB 
# DOCUMENT THAT'S OPENED WITH IT. A bookmarks file is inserted into 
# the book. I know of no way at this time to prevent it from doing so 
# short of turning off all write bits on the files.

# This script is a crude solution, let ebook-viewer touch a junk copy 
# of the book in /tmp
