Hi, I recently upgraded Rhino from version 1.8.0 to 1.8.1, but encountered a build issue with the message "no main manifest attribute." It appears that Rhino is no longer an executable JAR file, as the MANIFEST.MF is missing the Main-Class attribute. Additionally, I cannot find the main class within this JAR file. Is this change intentional as part of the new release, or could there be an issue? Thanks.
