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.

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

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.

This package aims to help client-server software development teams achieve full functional test coverage. It makes it possible to run several instances of the full software stack on the same machine to functionally test complex network configurations locally. It provides the following features:

• Redirects all network communication to happen over Unix sockets.

• Support for IPv4 and IPv6 socket and addressing emulation.

• Ability to capture network traffic in pcap format.

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

This package provides tools to test your PAM application or module. For testing PAM applications, a simple PAM module called pam_matrix is provided. For testing PAM modules, see the pamtest library. One can combine it with the CMocka unit testing framework or use the provided Python bindings to write tests for modules in Python.

Tevent is an event system based on the talloc memory management library. It is the core event system used in Samba. The low level tevent has support for many event types, including timers, signals, and the classic file descriptor events.

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 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.

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.

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.

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.

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.

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

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.

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.

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.

Gerbil mode provides font-lock, indentation, navigation, and REPL for Gerbil code within Emacs.

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.

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

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

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.
