ADODB is a set of advanced PHP database abstraction classes. It supports MySQL, PostgreSQL, Interbase/Firebird, Informix, Sybase SQL Anywhere, Oracle, MS SQL 7 and 2000, SAP DB, Sybase, DB2, FrontBase, Foxpro, Access, Netezza, LDAP, ODBTP, ADO, and generic ODBC. A metatype system is built in, making it possible to figure out that types such as CHAR, TEXT, and STRING are equivalent in different databases. It also features portable database creation, database-backed session support (with encryption), SQL performance monitoring, and database health checks.
The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware. It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
The AVI player is a plug-in for XMMS, giving it the ability to play Windows AVI (including DivX ;-)) and ASF files on your Linux or FreeBSD box. You can simply add movies to your playlist and the plug-in will call aviplay to play the movie files. Many aviplay options are supported, such as fullscreen playback and true hardware acceleration on XFree86 4.x.x.
AdaCGI is an Ada95 interface to the "Common Gateway Interface" (CGI). AdaCGI makes it easier to create Ada95 programs that can be invoked by World Wide Web (WWW) HTTP servers using the standard CGI interface. Using it, you can create Web applications using Ada95 to perform queries or other processing by request from a WWW user.
'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).
AutoOpts is an integrated part of AutoGen. Based on a very simple option description file, it will process configuration files, environment variables, command line options, text strings passed by client programs, and will make the results easily accessible to the client program. It will also produce a man page and the info-doc invoking section automatically.
