+# Inherit this bbclass for each java recipe that builds a Java library (jar file[s]).
+#
+# It automatically adds important build dependencies, defines JPN (Java Package Name)
+# a package named ${JPN} whose contents are those of ${datadir}/java (the jar location).
+#
+# The JPN is basically lib${PN}-java but takes care of the fact that ${PN} already
+# starts with "lib" and/or ends with "-java". In case the "lib" prefix is part of
+# your package's normal name (e.g. liberator) the guessing is wrong and you have
+# to set JPN manually!
