Chibi-Scheme is a very small library with no external dependencies 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.

Loko Scheme is intended to be a platform for application and operating system development. It is written purely in Scheme and some assembler (i.e. no C code at the bottom). Both the R6RS and the R7RS standards are supported.

TR7 is a lightweight Scheme interpreter that implements the revision R7RS small of scheme programming language.

It is meant to be used as an embedded scripting interpreter for other programs. A lot of functionality in TR7 is included conditionally, to allow developers freedom in balancing features and footprint.

SLIB is a portable Scheme library providing compatibility and utility functions for all standard Scheme implementations.

GNU/MIT Scheme is an implementation of the Scheme programming language. It provides an interpreter, a compiler and a debugger. It also features an integrated Emacs-like editor and a large runtime library.

Revised^7 Report of the Algorithmic Language Scheme adapted to Texinfo format.

femtolisp is a scheme-like lisp implementation with a simple, elegant Scheme dialect. It is a lisp-1 with lexical scope. The core is 12 builtin special forms and 33 builtin functions.

Owl Lisp is a simple programming language. It is intended to provide a portable system for writing standalone programs in a subjectively pleasant dialect of Lisp. It has a minimal core and runtime, purely functional operation, and support for asynchronous evaluation.

TinyScheme is a light-weight Scheme interpreter that implements as large a subset of R5RS as was possible without getting very large and complicated.

It's meant to be used as an embedded scripting interpreter for other programs. As such, it does not offer an Integrated Development Environment (IDE) or extensive toolkits, although it does sport a small (and optional) top-level loop.

As an embedded interpreter, it allows multiple interpreter states to coexist in the same program, without any interference between them. Foreign functions in C can be added and values can be defined in the Scheme environment. Being quite a small program, it is easy to comprehend, get to grips with, and use.

This is a R7RS Scheme implementation designed to run within a Common Lisp environment.

Unsyntax is an implementation of the Scheme programming language, specifically of its R7RS standard, and includes a number of extensions. Unsyntax evaluates Scheme expressions and compiles and runs Scheme programs by first expanding them into a minimal dialect of R7RS (small) without any syntactic extensions. The resulting expression or program is then evaluated by an existing Scheme implementation.

Byobu is a Japanese term for decorative, multi-panel screens that serve as folding room dividers. The Byobu software includes an enhanced profile, configuration utilities, and system status notifications for the GNU Screen window manager as well as the Tmux terminal multiplexer.

reptyr is a utility for taking an existing running program and attaching it to a new terminal. Started a long-running process over ssh, but have to leave and don't want to interrupt it? Just start a screen, use reptyr to grab it, and then kill the ssh session and head on home.

abduco provides session management i.e. it allows programs to be run independently from their controlling terminal. That is, programs can be detached---run in the background---and then later reattached.

dtach is a tiny program that emulates the detach feature of screen, allowing you to run a program in an environment that is protected from the controlling terminal and attach to it later.

GNU Screen is a terminal window manager that multiplexes a single terminal between several processes. The virtual terminals each provide features such as a scroll-back buffer and a copy-and-paste mechanism. Screen then manages the different virtual terminals, allowing you to easily switch between them, to detach them from the current session, or even splitting the view to show two terminals at once.

Scribus is a desktop publishing (DTP) application and can be used for many tasks; from brochure design to newspapers, magazines, newsletters and posters to technical documentation. Scribus supports professional DTP features, such as CMYK color and a color management system to soft proof images for high quality color printing, flexible PDF creation options, Encapsulated PostScript import/export and creation of four color separations, import of EPS/PS and SVG as native vector graphics, Unicode text including right to left scripts such as Arabic and Hebrew via FreeType.

lsscsi lists SCSI logical units or SCSI targets. It can also list NVMe namespaces or controllers and show the relationship between a device's primary node name, its SCSI generic (sg) node name and its kernel name.

Libiscsi is a client-side library to implement the iSCSI protocol that can be used to access the resources of an iSCSI target. It is fully asynchronous with regards to iSCSI commands and SCSI tasks, but a synchronous layer is also provided for ease of use for simpler applications.

sg3-utils is a collection of utilities for devices that use the Small Computer System Interface (SCSI) command set. It includes utilities to read data from, write data to, control, modify, and query the state of SCSI devices.

For example, this package provides command-line tools to:

• copy data based on dd syntax and semantics (called sg_dd, sgp_dd, and sgm_dd)

• check INQUIRY data and VPD pages (sg_inq)

• check mode and log pages (sginfo, sg_modes, and sg_logs)

• spin up and down disks (sg_start)

• do self-tests (sg_senddiag)

• parse sense data (sg_decode_sense)

• and perform various other functions.

In addition, this package includes a library, called libsgutils, which can be used in C and C++ programs to interact with SCSI devices.

SDL_net is a small, cross-platform networking library for SDL.

SDL_gfx provides graphics drawing primitives, rotozoom and other supporting functions for SDL.

MikMod is able to play a wide range of module formats, as well as digital sound files. It can take advantage of particular features of your system, such as sound redirection over the network.
