Where can I get the documentation for the Eclipse "Workbench" in PDF form?

(The [Eclipse FAQ](http://wiki.eclipse.org/FAQ_Can_I_get_my_documentation_in_PDF_form,_please?) says that the documentation for the Eclipse "SDK" (I assume this is the same as the Eclipse "Workbench") is available in PDF format from eclipse.org, but I can't find it anywhere.)
