       Javahelper tool to add or update manifests in a jar file. It can be used in two modes. If passed jar
       files, it will only process these jar files. Otherwise it will update all jar files in the packages it
       acts on.

       When processing a package, the debhelper(7) exclude option will make jh_manifest ignore matching jar
       files.

       An example debian/manifest file:

        # use the symlink so we do not have to update with the next upstream release.
        usr/share/java/my.jar:
         Class-Path: dep1.jar dep2.jar
         Main-Class: some.awesome.Class
        usr/share/java/dep2.jar:
         Class-Path: dep1.jar

       debian/package.manifest (or debian/manifest)
           This  file  consist  of a list of jar files and values to add to their manifests. Values in this file
           will take precedence over values in the original manifest (and command line arguments over values  in
           this file).

           It  is  allowed to list a link in this file instead of an actual jar file, provided that the link can
           be resolved when jh_manifest processes it.

           If a jar file is listed here cannot be found, jh_manifest will print a warning, unless the  jar  file
           has been excluded.

           As  of  javahelper  >=  0.32,  you may add comments in this file. If the line starts with a "#" it is
           completely ignored.

           This file is ignored if jh_manifest is passed jar files via command line.

-cclasspath, --classpath=classpath
           Sets the Class-Path attribute of all processed jar files to classpath.

           If not passed, then the CLASSPATH environment variable will be used in the given jar file do not have
           a Class-Path attribute.

       -mclass, --main=class
           Sets the Main-Class attribute to class in all processed jar files.

       --javaopts=options
           Sets the Debian-Java-Parameters to options in all processed jar files.  This  attribute  is  used  by
           jarwrapper to start java with extra options (e.g. to make more memory available).

       -j/path/to/java/home, --java-home=/path/to/java/home
           Sets  the  Debian-Java-Home  attribute to /path/to/java/home in all processed jars. This attribute is
           used by jarwrapper to determine which JVM to use.
