YAB
Yet Another Buildtool
In order to get the bleeding edge version of the code, you need to install Subversion and check out the source using the following command:
svn co --username anonymous http://depthfirst.no-ip.info:8080/svn/public/yab/trunk <local directory>
If it asks you for a password, just hit Enter.
Since Subversion is implemented on top of WebDAV, you may browse the most recent version of the code here.
