+    (description
+     "Agda is a dependently typed functional programming language: it has
+inductive families, which are similar to Haskell's GADTs, but they can be
+indexed by values and not just types.  It also has parameterised modules,
+mixfix operators, Unicode characters, and an interactive Emacs interface (the
+type checker can assist in the development of your code).  Agda is also a
+proof assistant: it is an interactive system for writing and checking proofs.
+Agda is based on intuitionistic type theory, a foundational system for
+constructive mathematics developed by the Swedish logician Per Martin-Löf.  It
+has many similarities with other proof assistants based on dependent types,
+such as Coq, Epigram and NuPRL.")

-Subject: [PATCH] Fix test_too_many_fields with Python 3.5
-
-taken from https://github.com/r1chardj0n3s/parse/pull/34
-
-Python versions before 3.5 had a limit of 100 groups in regular
-expressions. This limit was removed during 3.5 development:
-
-http://bugs.python.org/issue22437
-https://hg.python.org/cpython/rev/0b85ea4bd1af
-
-The test_too_many_fields test asserts that the limit exists by
-attempting to parse a string with 15 fields, which triggers the 100
-named groups limit.
-
-Adjust the test so that if first checks to see whether the limit of 100
-named groups exists, and only assert that parsing 15 fields fails if
-that is the case.

+2 (@dfn{HTTP/2}).
+
+A reusable C library provides the HTTP/2 framing layer, with several tools built
+on top of it:
+
+@itemize
+@item @command{nghttp}, a command-line HTTP/2 client.  It exposes many advanced
+and low-level aspects of the protocol and is useful for debugging.
+@item @command{nghttpd}, a fast, multi-threaded HTTP/2 static web server that
+serves files from a local directory.
+@item @command{nghttpx}, a fast, multi-threaded HTTP/2 reverse proxy that can be
+deployed in front of existing web servers that don't support HTTP/2.
+Both @command{nghttpd} and @command{nghttpx} can fall back to HTTP/1.1 for
+backwards compatibilty with clients that don't speak HTTP/2.
+@item @command{h2load} for benchmarking (only!) your own HTTP/2 servers.
+@item HTTP/2 uses a header compression method called @dfn{HPACK}.
+nghttp2 provides a HPACK encoder and decoder as part of its public API.
+@item @command{deflatehd} converts JSON data or HTTP/1-style header fields to
+compressed JSON header blocks.
+@item @command{inflatehd} converts such compressed headers back to JSON pairs.
