Downloadsvn

From Noah.org

This allows you to download files directly from SVN. It should give you a download and not open in the browser.
This is probably not very secure.

/**
 * This grabs a file from SVN and forces a download (instead of displaying it in
 * the browser). This assumes that 'svn cat' will work on the given filename. This
 * is a hack to force most browsers to download and save a file instead of trying
 * to display the file contents. This is especially helpful with PDF and image
 * files when you want to just download the file and not view it. This usually
 * works with IE and Mozilla. Based on http://elouai.com/force-download.php
