-;;; Commentary:
-
-;; Information about packages and generations is passed to the elisp
-;; side in the form of alists of parameters (such as ‘name’ or
-;; ‘version’) and their values.
-
-;; ‘entries’ procedure is the “entry point” for the elisp side to get
-;; information about packages and generations.
-
-;; Since name/version pair is not necessarily unique, we use
-;; `object-address' to identify a package (for ‘id’ parameter), if
-;; possible. However for the obsolete packages (that can be found in
-;; installed manifest but not in a package directory), ‘id’ parameter is
-;; still "name-version" string. So ‘id’ package parameter in the code
-;; below is either an object-address number or a full-name string.
