Arabeske is a special kind of vector drawing software. It has a limited set of shapes but is extremely specialised towards complex symmetric interlaced drawings, like those traditionally found in Arabic architecture. It is not a texture editor, but rather a pattern generator. It exports in EPS, PNG, and POV-Ray formats.
Apsfilter is a magic printfilter, allowing you to print different document types "automagically" without having to convert them manually into something which is understood by your printer. Apsfilter is a mature and powerful printing solution for any flavor of Unix running lpd or LPRng. It supports the latest GhostScript version and 3rd-party printer drivers (such as hpijs, ijs, hpdj, pcl3, and gimp-print). It autodetects lots of file, archive, and compression types. It supports printing on local as well as on Appletalk, Unix, and Windows remote printers. General and "per printer-queue" based config files allow you to configure the printer for your needs. The lpr command line options allow you to change printing parameters like print quality, orientation, duplex mode, etc. "on the fly" without having to edit any config file. A SETUP script helps you to test various supported ghostscript drivers prior installation, makes the necessary entries in /etc/printcap, creates spool directories, and creates apsfilter default config files as needed. A handbook in HTML is available. Several tools are also included: "aps2file" allows you to print to a file via apsfilter, "apspreview" previews files as generated by apsfilter using gv and friends, and "apsfilter-bug" assists you in doing bug and problem reports.
APSR is a network testing tool designed to send and receive arbitrary network packets. Its main purposes are firewall, security, routing, and a lot of other tests. It can also be used to analyze your network. The project is split into three main programs: apsend to create and send packets, aprecv to dump the network traffic, and the apsrlib which provides the appropriate low-level functions. A very wide range of protocols are supported by the aprecv program. The application layer is implemented through modules using a simple API. Modules can be written in Perl, Ruby, C, or PCL (a special-purpose packet construction language).
Aps is a small tool for analyzing network traffic. It prints out a great deal of information about the relevant protocols including TCP, UDP, ARP, and ICMP. It allows you to filter IP addresses, hardware addresses, ports, and specific protocols. It comes with a little GTK-GUI displaying packet counters for each protocol.
APRIL is a symbolic programming language that is designed for writing mobile, distributed and agent-based systems especially in an Internet environment. It has advanced features such as a macro sub-language, asynchronous message sending and receiving, code mobility, pattern matching, higher-order functions and strong typing. The language is compiled to byte-code which is then interpreted by the APRIL runtime-engine. APRIL now requires the InterAgent Communications Model (ICM) to be installed before it can be installed.
Applixware is a fully integrated suite of desktop productivity tools that runs on Linux (Intel, Alpha, & PPC), with versions available for virtually every other major operating system. Included in the suite are tools for word processing and document publishing, spreadsheets, business graphics, graphics editing, data access, and email. With Applixware, you can create compound live-linked documents simply and efficiently. Applixware also comes with a full programming environment and supports multiple windows operating simultaneously.
'App' is a preprocessor for C++ that accepts as input arbitrary C++ code that may contain embedded constructs for specifying algebraic data types and associated pattern matching operations, and produces as output the same code with all such constructs translated to normal C++. What app essentially does is provide for C++ pretty much the same capabilities that functional languages have regarding algebraic types. 'Applib' is the associated runtime library that supports the core run time requirements of the translated code, and which provides additional utilities (applib is covered by the LGPL).
