+# package or not, in which distribution it is contained
+# or if it is not contained it obtains information
+# from tasks file about home page, license, WNPP etc.
+
+# This is just a test how we should read tasks files
+# using python-debian to make sure everything is
+# processed nicely
+#
+# You should give the path to a tasks file at command
+# line for this simple test
