+;;; 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.
