+#
+# @param packages
+#   Specifies which package(s) to pin.
+#
+# @param priority
+#   Sets the priority of the package. If multiple versions of a given package are available, `apt-get` installs the one with the highest 
+#   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).
+#
+# @param component
+#   Names the licensing component associated with the packages in the directory tree of the Release file.
