The following document purports to explain how to set the Java CLASSPATH
for all platforms.

http://download.oracle.com/docs/cd/E17409_01/javase/tutorial/essential/environment/paths.html

However, there is no information about the syntax of the CLASSPATH, and
in particular how to separate multiple path entries. Near the bottom,
the document links to a "Setting the class path" technical note, below.

http://download.oracle.com/docs/cd/E17409_01/javase/6/docs/technotes/tools/windows/classpath.html

This technical note does not say so, but it is only valid for the
Windows platform. Since the CLASSPATH path delimiter is different for
Unix-based systems, this is misleading for someone trying to set the
CLASSPATH on such a system.

It would be nice to (1) link to a technical note for Unix platforms as
well as the Windows node, and (2) clearly label the Windows technical
note as for Windows platforms only, or to mention that on Unix-based
systems multiple path entries are separated by colon, not by semi-colon.
