This daemon allows (Samba) hosts to be found by Web Service Discovery Clients. It also implements the client side of the discovery protocol which searches for devices implementing WSD.

Ldb is a LDAP-like embedded database built on top of TDB. What ldb does is provide a fast database with an LDAP-like API designed to be used within an application. In some ways it can be seen as a intermediate solution between key-value pair databases and a real LDAP database.

Some projects, such as a file server, need privilege separation to be able to switch to the user who owns the files and do file operations on their behalf. This package convincingly lies to the application, letting it believe it is operating as root and even switching between UIDs and GIDs as needed. You can start any application making it believe it is running as root. This package provides the following features :

• Allows uid switching as a normal user.

• Start any application making it believe it is running as root.

• Support for user/group changing in the local thread using the syscalls (like glibc).

• Intercepts seteuid and related calls and simulates them in a way transparent to the application.

cifs-utils is a set of user-space utilities for mounting and managing CIFS shares using the Linux kernel CIFS client.

This package makes it possible on most UNIX platforms to contact your own DNS implementation in your test environment. It requires socket_wrapper to be able to contact the server. Alternatively, the wrapper is able to fake DNS queries and return valid responses to your application. It provides the following features:

• Redirects name queries to the nameservers specified in your resolv.conf.

• Can fake DNS queries using a simple formatted DNS hosts file.

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.

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.

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.

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.

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.

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.

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.

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.

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.

HOP is a multi-tier programming language for the Web 2.0 and the so-called diffuse Web. It is designed for programming interactive web applications in many fields such as multimedia (web galleries, music players, ...), ubiquitous and house automation (SmartPhones, personal appliance), mashups, office (web agendas, mail clients, ...), etc.

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

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

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

Stalin is an aggressively optimizing whole-program compiler for Scheme that does polyvariant interprocedural flow analysis, flow-directed interprocedural escape analysis, flow-directed lightweight CPS conversion, flow-directed lightweight closure conversion, flow-directed interprocedural lifetime analysis, automatic in-lining, unboxing, and flow-directed program-specific and program-point-specific low-level representation selection and code generation.

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.

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.

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.

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.
