#[test]
/// The [`jarsigner`] tool has two purposes:
/// * To sign Java Archive (JAR) files.
/// * To verify the signatures and integrity of signed JAR files.
///
/// The JAR feature enables the packaging of class files, images, sounds, and other digital data
/// in a single file for faster and easier distribution. A tool named jar enables developers to
/// produce JAR files. (Technically, any zip file can also be considered a JAR file, although when
/// created by the jar command or processed by the jarsigner command, JAR files also contain a
/// META-INF/MANIFEST.MF file.)
