In order to install cfengine, you should first ensure that the following
packages are installed.
Berkeley DB 3.2 or later http://www.sleepycat.com
The preferred method of installation is then
tar zxf cfengine-x.x.x.tar.gz
This results in binaries being installed in `/usr/local/sbin'.
Since this is not necessarily a local file system on all hosts, users
are encouraged to keep local copies of the binaries on each host, inside
the cfengine trusted work directory.
