+# @ECLASS_VARIABLE: JAVADOC_CLASSPATH
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# Comma or space separated list of java packages that are needed for generating
+# javadocs. Can be used to avoid overloading the compile classpath in multi-jar
+# packages if there are jar files which have different dependencies.
+#
+# @CODE
+# Example:
+# 	JAVADOC_CLASSPATH="
+# 		jna-4
+# 		jsch
+# 	"
+# @CODE
+
+# @ECLASS_VARIABLE: JAVADOC_SRC_DIRS
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# An array of directories relative to ${S} which contain the sources of
+# the application. It needs to sit in global scope; if put in src_compile()
+# it would not work.
+# It is needed by the java-pkg-simple.eclass to decide whether to call ejavadoc
+# or not. If this variable is defined then java-pkg-simple_src_compile will not
+# call ejavadoc automatically. ejavadoc has then to be called explicitly from
+# the ebuild. It is meant for usage in multi-jar packages in order to avoid an
+# extra compilation run only for producing the javadocs.
+#
+# @CODE
+# Example:
+#	JAVADOC_SRC_DIRS=(
+#	    "${PN}-core"
+#	    "${PN}-jsch"
+#	    "${PN}-pageant"
+#	    "${PN}-sshagent"
+#	    "${PN}-usocket-jna"
+#	    "${PN}-usocket-nc"
+#	    "${PN}-connector-factory"
