About Svnengine

As the name suggests, Svnengine purpose is to make integration between SVN and Cfengine easy. While working with Cfengine, there are many steps that are repetitive, boring and error prone. With Svnengine, the system administrator can create cfengine class in a more automated manner.

The principle of operation is simple. Files and attributes of files are stored in svn repository. If a file is added with svnengine, properties will be set for mode, owner, etc. Each files added into a directory can be used to generate the cfengine class file automaticaly. This file can be added to the cfengine server, and apply files to servers.

It's also usefull for testing. For example, you can apply a class even without a cfengine server. Also, you can change configuration files directly on the filesystem and gather changes by using the collect feature, and then commit.

Bet you will love it!
