+# Notes about the ideas behind packaging:
+# 1) User should install openjdk-6-jre. This is a provider of 'java2-runtime'.
+# 2) This lets package mgmt install: openjdk-6-java
+# -> openjdk-6-vm-shark|openjdk-6-vm-zero|openjdk-6-vm-cacao -> openjdk-6-common
+#
+# With opkg the zero VM is chosen which is good b/c that is the best known (= compatible)
+# runtime. Installing other runtimes side-by-side is possible. Through jvm.cfg the following
+# order of precedence is enforced: zero, shark, cacao. User can chose a different runtime
+# by adding '-shark' or '-cacao' to the Java command (or by deinstalling an otherwise preferred
+# runtime)
+# 3) All other packages, including -jdk, are optional and not needed for normal Java apps.
