Using SVN
First for newbies to SVN like me - this piece of software is a must for keeping track of updates to any electronic documents. For you folks it works using a simple checkout & update process.
First off, install Tortoise SVN. You may need to reboot (I can't remember if I did).
Your first checkout.
These steps will download your first copy of the pageflip repository.
Next, create a folder to download pageflip into and right click on it to get this menu :-

Select SVN Checkout and in the following dialog set the URL of the repository to http://pageflip.zeropain.com/svn/
The checkout directory should be inserted for you. Leave everything else as shown.

Click ok and the following dialog will display showing the files being downloaded and finally the revision of the repository. The download is very quick.

Notice above it says completed at Revision 1. The repository tracks it's own revision numbers - you can actually checkout any revision you like, using the previous dialog, but the default action is to checkout the latest version.
After you have checked out pageflip your folder will now have a green tick on it like this:-

And that is all there is to it.
Obtaining pageflip updates
Right click on the folder where you do your checkouts then select SVN Update from the popup menu :-

The update dialog will run and will list all the changes it makes (if any have been added to the repository since your last update or first checkout).

SVN Commit
Only I am allowed to do SVN commits. :-)
