This package provides a library to disable resource limits and other privilege dropping, i.e. disabling chroot, prctl, pledge and setrlmit system calls. This package aims to help running processes which are dropping privileges or are restricting resources in test environments. A disabled call always succeeds (i.e. returns 0) and does nothing.

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.

Talloc is a hierarchical, reference counted memory pool system with destructors. It is the core memory allocator used in Samba.

The Point-to-Point Protocol (PPP) provides a standard way to establish a network connection over a serial link. At present, this package supports IP and IPV6 and the protocols layered above them, such as TCP and UDP.

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.

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.

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.

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.

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.

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, 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.

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.

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

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.

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.

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.

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.

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.

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.

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.

Scheme 9 from Empty Space (S9fES) is a mature, portable, and comprehensible public-domain interpreter for R4RS Scheme offering:

• bignum arithmetics

• decimal-based real number arithmetics

• support for low-level Unix programming

• cursor addressing with Curses

• basic networking procedures

• an integrated online help system

• loads of useful library functions

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.
