17 # java-pkg.eclass and java-pkg-opt.eclass as well as from ebuilds.

19 # @warning
20 # You probably don't want to inherit this directly from an ebuild. Instead,
21 # you should inherit java-ant for Ant-based Java packages, java-pkg for other
22 # Java packages, or java-pkg-opt for packages that have optional Java support.
