SmartEiffel is the GNU Eiffel Compiler. It is intended to be a complete, though small and very fast, Eiffel compiler. The current distribution includes an Eiffel to C compiler, documentation tools, a pretty printer, and various other tools including an Eiffel debugger. It also includes a large library of classes distributed under the terms of the MIT/X Consortium License. Eiffel is an advanced object-oriented programming language that emphasizes the design and construction of high-quality and reusable software.
SANE stands for "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware (flatbed scanner, handheld scanner, video and still cameras, framegrabbers, etc.). The SANE standard is public domain and its discussion and development are open to everybody. The source code is written for UNIX (including Linux) and is available under the GPL, but commercial applications and backends are welcome. The package contains the libraries, net support, and scanimage. The X frontends xscanimage and xcam can be found in sane-frontends.
ePerl interprets an ASCII file bristled with Perl 5 program statements by evaluating the Perl 5 code while passing through the plain ASCII data. It can operate in various ways: As a stand-alone Unix filter or integrated Perl 5 module for general file generation tasks and as a powerful Webserver scripting language for dynamic HTML page programming.
The Free Pascal Compiler is a Turbo Pascal 7.0 and Delphi-compatible 32/64 bit Pascal Compiler. It comes with a fully TP 7.0-compatible run-time library. Some extensions have been added to the language, like function overloading. Shared libraries can be linked. Basic Delphi support is implemented with classes, exceptions, RTTI, and ansistrings. A Free Component Library (FCL) is available with the base classes. Bindings for X11, ncurses, GTK, OpenGL, zlib, mysql, interbase and postgres are available.
XForms is a GUI toolkit based on Xlib. It comes with a rich set of objects such as buttons, browsers, sliders, and menus integrated into an elegant event/object callback execution model that allows for fast and easy construction of X applications. In addition, the library supports loading and writing images, format conversion, and simple image processing. It consists of a flexible set of C-routines that can be used in C and C++ programs, is efficient and portable, and runs on all major Unix platforms and OpenVMS, OS/2, and Windows NT.
