+# @param priority

+# priority number (subject to dependency constraints). Valid options: an integer.
+#
+# @param release
+# Tells APT to prefer packages that support the specified release. Typical values include 'stable', 'testing', and 'unstable'.
+#
+# @param release_version
+# Tells APT to prefer packages that support the specified operating system release version (such as Debian release version 7).
