| org.eclipse.perfmsr.core code can be found in the perfmsr.jar loaded as binary in this | 
 | project. Since this is optional, we needed to be able to compile without the true | 
 | plugin being available. So we created the stub jar containing just what we needed. | 
 |  | 
 | If there is a need to change anything in the stub jar, you will need to checkout | 
 | the folder org.eclipse.jem.util/org.eclipse.perfmsr.core.stub. This will then | 
 | be a separate project. You can then make the changes there, and then following the | 
 | README in that project to create and commit the changes.  | 
 |  | 
 | The jar is in this project's classpath, but it is not exported and is not in | 
 | the plugin.xml or build.properties. This means it will be available for compilation | 
 | but it won't show up in the runtime workbench. |
