Using SVN to Get the Code
The source code on this website is available for anyone to download. You don't have to wait until a new build is made available. In fact, I don't expect to be making a downloadable build available very regularly at all. To get the latest code, you should use SVN to access the code directly from the repository.
To download the code you'll need a subversion (svn) client. Subversion is a version control system that allows you to track changes made on code, and allows several developers to change the same file at the same time without chaos ensuing.
Getting Subversion
If you don't already have a subversion client, then you can either download a command-line version from http://subversion.tigris.org/project_packages.html (versions are available for almost all popular operating systems).
Alternatively, if you prefer a friendly user interface and you are using Windows, then have a look at TortoiseSVN. It integrates into your Windows folder views and provides subversion commands through context-menu commands in Explorer.
Getting the Code
To get the code, you'll need to do a subversion checkout. The address of the code to checkout is
svn://www.iprventures.com/libs
If you're using the command-line svn, then you'll need something like:
svn co svn://www.iprventures.com/libs iprvcode
where iprvcode is the name of the directory on your machine that you want to put the downloaded code.
