-# This command creates a <target_name>.jar.  It compiles the given
-# source files (source) and adds the given resource files (resource) to
-# the jar file.  Source files can be java files or listing files
-# (prefixed by '@').  If only resource files are given then just a jar file
-# is created.  The list of include jars are added to the classpath when
-# compiling the java sources and also to the dependencies of the target.
-# INCLUDE_JARS also accepts other target names created by add_jar.  For
-# backwards compatibility, jar files listed as sources are ignored (as
-# they have been since the first version of this module).

-# The default OUTPUT_DIR can also be changed by setting the variable

-# Optionally, using option GENERATE_NATIVE_HEADERS, native header files can be generated

-#
-# GENERATE_NATIVE_HEADERS option requires, at least, version 1.8 of the JDK.

-#
-#

-# This command will no longer be supported starting with version 10 of the JDK due
-# to the `suppression of javah tool <http://openjdk.java.net/jeps/313>`_.
-# Command ``add_jar(GENERATE_NATIVE_HEADERS)`` must be used instead.
-#
-# There are two main signatures for create_javah.  The first signature

-# ::
-#
-#    Example:
-#    Create_javah(GENERATED_FILES files_headers
-#      CLASSES org.cmake.HelloWorld
-#      CLASSPATH hello.jar
-#    )
-#
-#
-#

-#    Example:
-#    Create_javah(TARGET target_headers
-#      CLASSES org.cmake.HelloWorld
-#      CLASSPATH hello.jar
-#    )
-#
-#
-#
-# Both signatures share same options.
-#
-#  ``CLASSES <class>...``
-#    Specifies Java classes used to generate headers.
-#
-#  ``CLASSPATH <classpath>...``
-#    Specifies various paths to look up classes. Here .class files, jar files or targets
-#    created by command add_jar can be used.
-#
-#  ``DEPENDS <depend>...``
-#    Targets on which the javah target depends
-#
-#  ``OUTPUT_NAME <path>``
-#    Concatenates the resulting header files for all the classes listed by option CLASSES
-#    into <path>. Same behavior as option '-o' of javah tool.
-#
-#  ``OUTPUT_DIR <path>``
-#    Sets the directory where the header files will be generated. Same behavior as option
-#    '-d' of javah tool. If not specified, ${CMAKE_CURRENT_BINARY_DIR} is used as output directory.

+ install_jni_symlink(target_name DESTINATION destination [COMPONENT component])
+
+This command installs the TARGET_NAME JNI symlinks to the given
+DESTINATION.  It should be called in the same scope as add_jar() or it
+will fail.

+                     FILE <filename>
+                     DESTINATION <dir> [COMPONENT <component>])
+
+This command installs a target export file ``<filename>`` for the named jar
+targets to the given ``DESTINATION``. Its function is similar to that of
+:command:`install(EXPORTS ...)`.
+
+::
+
+ export_jars(TARGETS jars...
+             [NAMESPACE <namespace>]
+             FILE <filename>)
+
+This command writes a target export file ``<filename>`` for the named jar
+targets. Its function is similar to that of :command:`export(...)`.

+                )
+
+Create java documentation based on files or packages.  For more
+details please read the javadoc manpage.
+
+There are two main signatures for create_javadoc.  The first signature
+works with package names on a path with source files:
+
+::
+
+   Example:
+   create_javadoc(my_example_doc
+     PACKAGES com.example.foo com.example.bar
+     SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}"
+     CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
+     WINDOWTITLE "My example"
+     DOCTITLE "<h1>My example</h1>"
+     AUTHOR TRUE
+     USE TRUE
+     VERSION TRUE
+   )
+
+
+
+The second signature for create_javadoc works on a given list of
+files.
+
+::
+
+   create_javadoc(<VAR>
+                  FILES file1 [file2 ...]
+                  [CLASSPATH <classpath>]
+                  [INSTALLPATH <install path>]
+                  [DOCTITLE "the documentation title"]
+                  [WINDOWTITLE "the title of the document"]
+                  [AUTHOR TRUE|FALSE]
+                  [USE TRUE|FALSE]
+                  [VERSION TRUE|FALSE]
+                 )
+
+
+
+Example:
+
+::
+
+   create_javadoc(my_example_doc
+     FILES ${example_SRCS}
+     CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
+     WINDOWTITLE "My example"
+     DOCTITLE "<h1>My example</h1>"
+     AUTHOR TRUE
+     USE TRUE
+     VERSION TRUE
+   )
+
+
+
+Both signatures share most of the options.  These options are the same
+as what you can find in the javadoc manpage.  Please look at the
+manpage for CLASSPATH, DOCTITLE, WINDOWTITLE, AUTHOR, USE and VERSION.
+
+The documentation will be by default installed to
+
+::
+
+   ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>
+
+
+
+if you don't set the INSTALLPATH.
+
+::
+
+ create_javah(TARGET <target>
+              GENERATED_FILES <VAR>
+              CLASSES <class>...
+              [CLASSPATH <classpath>...]
+              [DEPENDS <depend>...]
+              [OUTPUT_NAME <path>|OUTPUT_DIR <path>]
+              )
+
+Create C header files from java classes. These files provide the connective glue
+that allow your Java and C code to interact.
+
+This command will no longer be supported starting with version 10 of the JDK due
+to the `suppression of javah tool <http://openjdk.java.net/jeps/313>`_.
+Command ``add_jar(GENERATE_NATIVE_HEADERS)`` must be used instead.
+
+There are two main signatures for create_javah.  The first signature
+returns generated files through variable specified by GENERATED_FILES option:
+
+::
+
+   Example:
+   Create_javah(GENERATED_FILES files_headers
+     CLASSES org.cmake.HelloWorld
+     CLASSPATH hello.jar
+   )
+
+
+
+The second signature for create_javah creates a target which encapsulates
+header files generation.
+
+::
+
+   Example:
+   Create_javah(TARGET target_headers
+     CLASSES org.cmake.HelloWorld
+     CLASSPATH hello.jar
+   )
+
+
+
+Both signatures share same options.
+
+ ``CLASSES <class>...``
+   Specifies Java classes used to generate headers.
+
+ ``CLASSPATH <classpath>...``
+   Specifies various paths to look up classes. Here .class files, jar files or targets
+   created by command add_jar can be used.
+
+ ``DEPENDS <depend>...``
+   Targets on which the javah target depends
+
+ ``OUTPUT_NAME <path>``
+   Concatenates the resulting header files for all the classes listed by option CLASSES
+   into <path>. Same behavior as option '-o' of javah tool.
+
+ ``OUTPUT_DIR <path>``
+   Sets the directory where the header files will be generated. Same behavior as option
+   '-d' of javah tool. If not specified, ${CMAKE_CURRENT_BINARY_DIR} is used as output directory.
