  util.SysInfo

public class SysInfo
extends java.lang.Object

Utility class for returning a processed system property. The properties are processed as follows: First all the points in this property are replaced with dashes and then the substring from the start to the first character that is not a letter, a digit, a dash or an underscore is taken. If we take, for instance, the system property os.name on Mac OS X, this will be Mac OS X, but the method get will return Mac.

This class is not only used by the CaGe program but also in the installation script. This package is packed into a separate jar named sysinfo.jar .
