+Common Lisp Support for libgpg-error
+------------------------------------
+
+Requirements:
+
+ASDF	Packaging Support
+CFFI	Foreign Function Interface
+
+Use with:
+
+> (asdf:operate 'asdf:load-op ':gpg-error)
+> (use-package :gpg-error)
+
+
+TODO
+----
+
+* We probably should define a condition base class.  Currently, we do
+  this in the user code only (eg in GPGME).
+
+* Some lispy convenience functions as need arises, for example for
+  output.

+;;; The following features work slightly differently:
