How to convert old "plugin.xml" to new "manifest.mf" file?

How to convert plugin.xml file to manifest.mf file as some tags like:

<runtime>
    <library name="aaa.jar">
        <export name="*"/>
    </library>
<runtime>

are seems to be ignored.

Here is some correspondence in the next document, but far from c开发者_如何学Pythonomplete reference.

Open the file in the plugin.xml editor. On the Overview Tab>Plug-in Content section there should be a link, "..., create an OSGi manifest"

The OSGi manifest is a set of headers describing the bundle, the bundles or packages that are dependencies, and the packages this bundle exports. ex:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Eclipse UI Tests
Bundle-SymbolicName: org.eclipse.ui.tests; singleton:=true
Bundle-Version: 3.6.0.qualifier
Bundle-ClassPath: uitests.jar
Bundle-Activator: org.eclipse.core.internal.compatibility.PluginActivator
Bundle-Vendor: Eclipse.org
Require-Bundle: org.eclipse.core.runtime.compatibility,
 org.eclipse.core.resources,
 org.eclipse.core.expressions,
 org.eclipse.ui,
 ...
Eclipse-AutoStart: true
Export-Package: org.eclipse.ui.tests.api,
 org.eclipse.ui.tests.helpers,
 org.eclipse.ui.tests.menus
Bundle-RequiredExecutionEnvironment: J2SE-1.4
