+    Akku.scm is a language package manager for Scheme.
+    It grabs hold of code and vigorously shakes it until it behaves properly.
+    - No complicated setup to point out where libraries are; Akku finds them!
+    - Separately declare dependencies and locked versions for your project.
+    - Convert R7RS libraries for use with Chez Scheme and other R6RS Scheme implementations.
+    - Numerous R6RS packages, as well as R7RS libraries mirrored from Snow.

+  <longdescription>
+    Bigloo is a Scheme implementation devoted to one goal: enabling Scheme
+    based programming style where C(++) is usually required.
+    Bigloo attempts to make Scheme practical by offering features usually
+    presented by traditional programming languages but not offered by Scheme
+    and functional programming. Bigloo compiles Scheme modules. It delivers
+    small and fast stand alone binary executables. Bigloo enables full
+    connections between Scheme and C programs.

+    miniKanren is an embedded Domain Specific Language for logic programming.
+    The core miniKanren language is very simple, with only three logical
+    operators and one interface operator.
+    miniKanren is designed to be easily modified and extended; extensions
+    include Constraint Logic Programming, probabilistic logic programming,
+    nominal logic programming, and tabling.

+  <longdescription>
+    Chez Scheme is both a programming language and an implementation
+    of that language, with supporting tools and documentation.
+
+    As a superset of the language described in the Revised6 Report on
+    the Algorithmic Language Scheme (R6RS), Chez Scheme supports all
+    standard features of Scheme, including first-class procedures,
+    proper treatment of tail calls, continuations, user-defined
+    records, libraries, exceptions, and hygienic macro expansion.
+
+    Chez Scheme also includes extensive support for interfacing with C
+    and other languages, support for multiple threads possibly running
+    on multiple cores, non-blocking I/O, and many other features.

+    Chibi-Scheme is a very small library intended for use as an extension
+    and scripting language in C programs. In addition to support for
+    lightweight VM-based threads, each VM itself runs in an isolated heap
+    allowing multiple VMs to run simultaneously in different OS threads.
+    Despite the small size, Chibi-Scheme attempts to do The Right Thing.
+    The default settings include:
+    - a full numeric tower, with rational and complex numbers
+    - full and seamless Unicode support
+    - low-level and high-level hygienic macros
+    - an extensible module system
+    Specifically, the default repl language contains all bindings from R7RS
+    small, available explicitly as the (scheme small) library. The language
+    is built in layers, however - see the manual for instructions on
+    compiling with fewer features or requesting a smaller language
+    on startup.

+    Cyclone Scheme is a brand-new compiler that allows real-world
+    application development using the R7RS Scheme Language standard.
+    We provide modern features and a stable system capable of generating
+    fast native binaries.
+    Cheney on the MTA is used by Cyclone's runtime to implement full tail
+    recursion, continuations, and generational garbage collection.
+    In addition, the Cheney on the MTA concept has been extended to allow
+    execution of multiple native threads. An on-the-fly garbage collector
+    is used to manage the second-generation heap and perform major
+    collections without "stopping the world".

+  <longdescription>
+    Fibers is a Guile library that implements a a lightweight concurrency
+    facility, inspired by systems like Concurrent ML, Go, and Erlang. A fiber
+    is like a "goroutine" from the Go language: a lightweight thread-like
+    abstraction. Systems built with Fibers can scale up to millions of
+    concurrent fibers, tens of thousands of concurrent socket connections, and
+    many parallel cores. The Fibers library also provides Concurrent ML-like
+    channels for communication between fibers.

+ <longdescription>
+		Gauche is an R5RS Scheme implementation developed to be a handy script
+		interpreter, which allows programmers and system administrators to write
+		small to large scripts for their daily chores. Quick startup, built-in
+		system interface, native multilingual support are some of my goals.
+
+		Gauche runs on several Unix-like platforms.

+  <longdescription>
+    Guile Config is a library providing a declarative approach to application
+    configuration specification. The library provides clean configuration
+    declaration forms, and processors that take care of: configuration file
+    creation; configuration file parsing; command-line parameter parsing using
+    getopt-long; basic GNU command-line parameter generation (--help, --usage,
+    --version); automatic output generation for the above command-line
+    parameters.

+    This is a library for GNU Guile to create language bindings via GObject
+    Introspection.
+    Guile GI has two primary components:
+    - The gi scheme modules: guile modules that provide functionality to
+    dynamically generate Scheme API from GObject typelib files.
+    - libguile-gi.so or libguile-gi.dll: a compiled module that contains glue
+    code to interface with GObject.
+    To create bindings, use the use-typelibs syntax found in the (gi) library.

+    NYACC, for Not Yet Another Compiler Compiler, is set of guile modules for

+    and pretty-printers using SXML trees as an intermediate representation.
+    It provides a decent C parser and a `FFI Helper' tool to help create Guile
+    Scheme bindings for C-based libraries.
+    It provides (partially implemented) compilers based on above mentioned
+    parsers to allow execution with Guile as extension languages.

+  <longdescription>
+    Guile-Reader is a simple framework for building readers for GNU Guile.
+    The idea is to make it easy to build procedures that extend Guile's read
+    procedure. Readers supporting various syntax variants can easily be
+    written, possibly by re-using existing "token readers" of a standard Scheme
+    readers. For example, it is used to implement Skribilo's R5RS-derived
+    document syntax.
+    Guile-Reader's approach is similar to Common Lisp's "read table", but
+    hopefully more powerful and flexible (for instance, one may instantiate as
+    many readers as needed).

+Subject: [PATCH 4/4] Run sigbits fixpoint based on use/def graph, not cfg
+
+* module/language/cps/specialize-numbers.scm (sigbits-ref): New helper.
+(invert-graph*): New helper.
+(compute-significant-bits): When visiting a term changes computed
+needed-bits for one of its definitions, we need to revisit the variables
+that contributed to its result (the uses), because they might need more
+bits as well.  Previously we were doing this by enqueueing predecessors
+to the term, which worked if the uses were defined in predecessors, or
+if all defining terms were already in the worklist, which is the case
+without loops.  But with loops, when revisiting a term, you could see
+that it causes sigbits to change, enqueue its predecessors, but then the
+predecessors don't change anything and the fixpoint stops before
+reaching the definitions of the variables we need.  So instead we
+compute the use-def graph and enqueue defs directly.

+  <longdescription>
+    Grow your Program - Racket's interactive mode encourages
+    experimentation, and quick scripts easily compose into larger
+    systems. Small scripts and large systems both benefit from native-code
+    JIT compilation. When a system gets too big to keep in your head, you
+    can add static types.  Grow your Language - extend Racket whenever you
+    need to. Mold it to better suit your tasks without sacrificing
+    interoperability with existing libraries and without having to modify
+    the tool chain. When less is more, you can remove parts of a language or
+    start over and build a new one.  Grow your Skills - whether you're just
+    starting out, want to know more about programming language applications
+    or models, looking to expand your horizons, or ready to dive into
+    research, Racket can help you become a better programmer and system
+    builder.

+  <longdescription>
+    Skribilo is a free document production tool that takes a structured
+    document representation as its input and renders that document in a variety
+    of output formats: HTML and Info for on-line browsing, and Lout and LaTeX
+    for high-quality hard copies.
+    The input document can use Skribilo's markup language to provide
+    information about the document's structure, which is similar to HTML or
+    LaTeX and does not require expertise. Alternatively, it can use a simpler,
+    "markup-less" format that borrows from Emacs' outline mode and from other
+    conventions used in emails, Usenet and text.
+    Lastly, Skribilo provides Guile Scheme APIs.
