+Prepare for packaging. This is "meta"-command which runs
+the following commands in order:
+
+  reap-clean
+  reap-make-distclean
+  reap-version
+
+The make-distclean command is not run if the project does
+not have any extensions, or is being prepared for a binary
+package. These commands prepare the project for packaging.
