+/**
+ * Prints a greeting which can be customized by building with resources and/or passing in command-
+ * line arguments.
+ *
+ * <p>Building and running this file will print "Hello world". Build and run the
+ * //examples/java-native/src/main/java/com/example/myproject:hello-world target to demonstrate
+ * this.</p>
+ *
+ * <p>If this is built with a greeting.txt resource included, it will replace "Hello" with the
+ * contents of greeting.txt. The
+ * //examples/java-native/src/main/java/com/example/myproject:hello-resources target demonstrates
+ * this.</p>
+ *
+ * <p>If arguments are passed to the binary on the command line, the first argument will replace
+ * "world" in the output. See //examples/java-native/src/test/java/com/example/myproject:hello's
+ * argument test.</p>
