<p>BusyBox combines tiny versions of many common UNIX utilities into a

single small executable. It provides replacements for most of the

utilities you usually find in GNU fileutils, shellutils, etc. The

utilities in BusyBox generally have fewer options than their

full-featured GNU cousins; however, the options that are included

provide the expected functionality and behave very much like their GNU

counterparts. BusyBox provides a fairly complete environment for any

small or embedded system.</p>

<p>BusyBox has been written with size-optimization and limited

resources in mind. It is also extremely modular so you can easily

include or exclude commands (or features) at compile time. This makes

it easy to customize your embedded systems. To create a working

system, just add some device nodes in /dev, a few configuration files

in /etc, and a Linux kernel.</p>

<p>The Common Workflow Language (CWL) is a specification for describing

analysis workflows and tools in a way that makes them portable and scalable

across a variety of software and hardware environments, from workstations to

cluster, cloud, and high performance computing (HPC) environments. CWL is

designed to meet the needs of data-intensive science, such as

bioinformatics, medical imaging, astronomy, physics, and chemistry.</p>

<p>Darcs is a distributed revision control system written in Haskell. In

Darcs, every copy of your source code is a full repository, which allows for

full operation in a disconnected environment, and also allows anyone with

read access to a Darcs repository to easily create their own branch and

modify it with the full power of Darcs' revision control. Darcs is based on

an underlying theory of patches, which allows for safe reordering and

merging of patches even in complex scenarios. For all its power, Darcs

remains a very easy to use tool for every day use because it follows the

principle of keeping simple things simple.  Darcs is free software

licensed under the GNU GPL.</p>

<p>The Evergreen Project develops an open source ILS (integrated library

system) used by hundreds of libraries across the world. The software, also

called Evergreen, is used by libraries to provide their public catalog

interface as well as to manage back-of-house operations such as

circulation (checkouts and checkins), acquisition and cataloging of

library materials, and sharing resources among groups of libraries and

consortia on the same Evergreen system.  Evergreen is designed to be

scalable and supports library operations ranging from a small high school

to large state-wide consortia.  Evergreen is released under

the <a href="http://www.gnu.org/licenses/gpl-2.0.html">GPLv2</a>-or-later.</p>

<p>Gevent is a fast, coroutine-based networking library for Python.

Gevent is used in network applications, including servers that scale

up to tens thousands of connections but without the complexity usually

associated with event-driven architecture.</p>

<p>Gevent provides light-weight &ldquo;green&rdquo; threads with a similar

interface as the standard “threading” and

“multiprocessing” packages.  The library includes a DNS

resolver, a WSGI server, a monkey patching utility to make 3rd party

protocol implementations cooperative and support for SSL sockets.</p>

<p>Git is a free and open source distributed version control system

  designed to handle everything from small to very large projects with

  speed and efficiency.</p>

  full revision tracking capabilities, not dependent on network access

  or a central server. Branching and merging are fast and easy to do.</p>

<p>Git is used for version control of files, much like tools such as

  Mercurial, Bazaar, Subversion, CVS, Perforce, and Visual SourceSafe.</p>
