;;; Error sources and codes are represented as keywords like
;;; :gpg-err-source-gpg and :gpg-err-unknown-packet.
;;;
;;; Errors are represented as lists '(SOURCE CODE).  Other
;;; representations are also accepted in some places.
;;;
;;; The following functions are defined which are not defined in the C API:
;;; gpg-err-source-as-key, gpg-err-source-as-value
;;; gpg-err-code-as-key, gpg-err-code-as-value
;;; gpg-err-canonicalize, gpg-err-as-value
;;; Conversion between keywords and values for error sources and codes.
;;; 
;;; The following functions from the C API are omitted:
;;; gpg-strerror-r
;;;
;;; The following features work slightly differently:
;;; *gpg-err-source-default* is a dynamic variable that can be set to
;;; change the default for gpg-error.
