+# @eclass-summary Eclass for Java sources without build instructions
+#
+# This class is intended to build pure Java packages from Java sources
+# without the use of any build instructions shipped with the sources.
+# There is no support for resources besides the generated class files,
+# or for generating source files, or for controlling the META-INF of
+# the resulting jar, although these issues may be addressed by an
+# ebuild by putting corresponding files into the target directory
+# before calling the src_compile function of this eclass.
