Paul,
As has been mentioned before, it may all be there to download, but it sure does take awhile grabbing all of those separate files one at a time from the several folders at that URL.
Your svn client will do the download for you. You could turn on compression if bandwidth is a problem for you.
Could a single compressed file be made available, like it was for many years ?? Or maybe an FTP URL be established, so as to grab the whole directory path and all of it's files and sub-directories ??
Single compressed source files, at least since I started working with Fractint in 1991 (or so), have only been available for the official releases and the occasional time when we needed to sync the source of the various developers. The use of an svn repository makes this unnecessary. How is using an FTP URL to provide access to the source tree any different than using svn? Are you pointing your web browser at the svn repository or are you using an svn client such as TortoiseSVN? Jonathan
