+Often you may want to answer questions like: ``Which revision of Guix am I
+using?'' or ``Which channels am I using?''  This is useful information in many
+situations: if you want to @emph{replicate} an environment on a different
+machine or user account, if you want to report a bug or to determine what
+change in the channels you are using caused it, or if you want to record your
+system state for reproducibility purposes.  The @command{guix describe}
+command answers these questions.
+
+When run from a @command{guix pull}ed @command{guix}, @command{guix describe}
+displays the channel(s) that it was built from, including their repository URL
+and commit IDs (@pxref{Channels}):
+
+@example
+$ guix describe
+Generation 10	Sep 03 2018 17:32:44	(current)
+  guix e0fa68c

+If you're familiar with the Git version control system, this is similar in
+spirit to @command{git describe}; the output is also similar to that of
+@command{guix pull --list-generations}, but limited to the current generation
+(@pxref{Invoking guix pull, the @option{--list-generations} option}).  Because
+the Git commit ID shown above unambiguously refers to a snapshot of Guix, this
+information is all it takes to describe the revision of Guix you're using, and

+Subject: [PATCH] Bug 699708 (part 1): 'Hide' non-replaceable error handlers
+ for SAFER
+
+We already had a 'private' dictionary for non-standard errors: gserrordict.
+
+This now includes all the default error handlers, the dictionary is made
+noaccess and all the prodedures are bound and executeonly.
+
+When running with -dSAFER, in the event of a Postscript error, instead of
+pulling the handler from errordict, we'll pull it from gserrordict - thus
+malicious input cannot trigger problems by the use of custom error handlers.
+
+errordict remains open and writeable, so files such as the Quality Logic tests
+that install their own handlers will still 'work', with the exception that the
+custom error handlers will not be called.
+
+This is a 'first pass', 'sledgehammer' approach: a nice addition would to allow
+an integrator to specify a list of errors that are not to be replaced (for
+example, embedded applications would probably want to ensure that VMerror is
+always handled as they intend).

-;;; Commentary:
-;;;
-;;; Public key cryptographic routines from GNU Libgcrypt.
-;;;;
-;;; Libgcrypt uses "canonical s-expressions" to represent key material,
-;;; parameters, and data.  We keep it as an opaque object to map them to
-;;; Scheme s-expressions because (1) Libgcrypt sexps may be stored in secure
-;;; memory, and (2) the read syntax is different.
-;;;
-;;; A 'canonical-sexp->sexp' procedure is provided nevertheless, for use in
-;;; cases where it is safe to move data out of Libgcrypt---e.g., when
-;;; processing ACL entries, public keys, etc.
-;;;
-;;; Canonical sexps were defined by Rivest et al. in the IETF draft at
-;;; <http://people.csail.mit.edu/rivest/Sexp.txt> for the purposes of SPKI
-;;; (see <http://www.ietf.org/rfc/rfc2693.txt>.)
