+/* SunVersion is used to compare java versions based on a string, as taken
+   from the registry. The strings look like "1.3", "1.3.1", "1.3.1_02" etc.
+   Versions such as "1.4.1_01a" are allowed although this is not specified.
+   1.4.1_01 < 1.4.1_01a < 1.4.1_01b < 1.4.1_02
+   Pre - release versions, such as 1.4.1-ea, 1.4.1-beta, 1.4.1-rc are recognized,
+   but are treated as minor to release versions:
+   1.4.0 > 1.4.2-beta
+   Pre releases relate this way
+   1.4.1-ea < 1.4.1-beta < 1.4.1-rc1
+
+   This class supports also a FreeBSD Java. This is currently necessary because
+   it also has the vendor string "Sun Microsystems Inc.".
+
+   An object acts as holder for the version string. That string may be present
+   even if the version could not be parsed. Then the version may not be compatible
+   to a SUN Java version.
+
+   An invalid object, that is, operator bool returns false, will always be
+   the lower version in a comparison. If two invalid objects are compared
+   then they are considered equal.
+
+   To test if the version is ok, that is this object can be compared to others,
+   use the bool conversion operator.
