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.

The iniParser C library reads and writes Windows-style .ini configuration files. These are simple text files with a basic structure composed of sections, properties, and values. While not expressive, they are easy to read, write, and modify.

The library is small, thread safe, and written in portable ANSI C with no external dependencies.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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

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.

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.
