Stand alone update commands as described
at
http://dev.eclipse.org/viewcvs/index.cgi/~checkout~/org.eclipse.platform.doc.isv/reference/misc/update_standalone.html?rev=1.1&content-type=text/html
are appropriate for updating any Eclipse
product, and require a restart.
Infocenter update commands are little
different, described in another document.
http://dev.eclipse.org/viewcvs/index.cgi/~checkout~/org.eclipse.platform.doc.isv/reference/misc/help_infocenter_update.html
They can be used to update a running
infocenter (do not require restart). The -command apply only exist
in the infocenter set of commands.
