Since 1992, Samba has provided secure, stable and fast file and print services for all clients using the SMB/CIFS protocol, such as all versions of DOS and Windows, OS/2, GNU/Linux and many others.

Samba is an important component to seamlessly integrate Linux/Unix Servers and Desktops into Active Directory environments using the winbind daemon.

XSane is a graphical interface for controlling a scanner and acquiring images from it. You can photocopy multi-page documents and save, fax, print, or e-mail your scanned images. It is highly configurable and exposes all device settings, letting you fine-tune the final result. It can also be used as a GIMP plugin to acquire images directly from a scanner.

XSane talks to scanners through the SANE back-end library, which supports almost all existing scanners.

SANE stands for "Scanner Access Now Easy" and is an API proving access to any raster image scanner hardware (flatbed scanner, hand-held scanner, video- and still-cameras, frame-grabbers, etc.). The package contains the library and drivers.

SANE stands for "Scanner Access Now Easy" and is an API proving access to any raster image scanner hardware (flatbed scanner, hand-held scanner, video- and still-cameras, frame-grabbers, etc.). The package contains the library, but no drivers.

Utsushi is a set of applications for image scanning with support for a number of EPSON scanners, including a compatibility driver to interface with software built around the SANE standard.

To enable auto-rotation functionality, install the tesseract-ocr and tesseract-ocr-tessdata-fast packages.

This SANE backend lets you scan documents and images from scanners and multi-function printers that speak eSCL (marketed as ``AirScan'') or WSD (or ``WS-Scan'').

Both are vendor-neutral protocols that allow ``driverless'' scanning over IPv4 and IPv6 networks without the vendor-specific drivers that make up most of the sane-backends collection. This is similar to how most contemporary printers speak the universal IPP.

Only scanners that support eSCL will also work over USB. This requires a suitable IPP-over-USB daemon like ipp-usb to be installed and configured.

Any eSCL or WSD-capable scanner should just work. sane-airscan automatically discovers and configures devices, including which protocol to use. It was successfully tested with many devices from Brother, Canon, Dell, Kyocera, Lexmark, Epson, HP, OKI, Panasonic, Pantum, Ricoh, Samsung, and Xerox, with both WSD and eSCL.

Scanbd stands for scanner button daemon. It regularly polls scanners for pressed buttons, function knob changes, or other events such as (un)plugging the scanner or inserting and removing paper. Then it performs the desired action(s) such as saving, copying, or e-mailing the image.

Actions can be fully customized through scripts, based on any combination of switch or knob settings. Events are also signaled over D-Bus and scans can even be triggered over D-Bus from foreign applications.

Scanbd talks to scanners through the SANE back-end library. This means that it supports almost all existing scanners, provided the driver also exposes the buttons.

Gambit consists of two main programs: gsi, the Gambit Scheme interpreter, and gsc, the Gambit Scheme compiler. The interpreter contains the complete execution and debugging environment. The compiler is the interpreter extended with the capability of generating executable files. The compiler can produce standalone executables or compiled modules which can be loaded at run time. Interpreted code and compiled code can be freely mixed.

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.

Scheme 48 is an implementation of Scheme based on a byte-code interpreter and is designed to be used as a testbed for experiments in implementation techniques and as an expository tool.

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.

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.

Gerbil is an opinionated dialect of Scheme designed for Systems Programming, with a state of the art macro and module system on top of the Gambit runtime. The macro system is based on quote-syntax, and provides the full meta-syntactic tower with a native implementation of syntax-case. It also provides a full-blown module system, similar to PLT Scheme's (sorry, Racket) modules. The main difference from Racket is that Gerbil modules are single instantiation, supporting high performance ahead of time compilation and compiled macros.

STklos is a free Scheme system mostly compliant with the languages features defined in R7RS small. The aim of this implementation is to be fast as well as light. The implementation is based on an ad-hoc Virtual Machine. STklos can also be compiled as a library and embedded in an application.

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.

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

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

GNU SCM is an implementation of Scheme. This implementation includes Hobbit, a Scheme-to-C compiler, which can generate C files whose binaries can be dynamically or statically linked with a SCM executable.

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

Pre-Scheme is a statically compilable dialect of Scheme, used to implement the Scheme 48 virtual machine. Scheme 48 ships with a Pre-Scheme to C compiler written in Scheme, and a runtime library which allows Pre-Scheme code to run as Scheme.

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.

String pattern-matching library for scheme48 based on the SRE regular-expression notation.

Gauche is a R7RS Scheme scripting engine aiming at being a handy tool that helps programmers and system administrators to write small to large scripts quickly. Quick startup, built-in system interface, native multilingual support are some of the goals. Gauche comes with a package manager/installer gauche-package which can download, compile, install and list gauche extension packages.

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 and between Scheme and Java programs.
