- Logging/console output facility.
- Command line parsing.
- Configuration file I/O.
- Database interface.
- IO multiplexing.
- Generic, serializable tree data structure.
- Perl-compatible regular expression pattern matching.
- String Filters.
- Template Engine, including Class templates.
- Advanced date and time handling (not restricted to the POSIX epoch, supporting time zone conversions).
- Generic byte string tokenizer.
- TCP socket API.
- Generic TCP client and server, message based client and server, and authenticated client and server.
- Support for the Cairo vector graphics API (http://www.cairographics.org/).
- Miscellaneous helpful and easy to use utility functions.

The GTK ADI Library is a GTK widget library that implements an ADI widget framework.

GTK ADI Library is an Advanced Document Interface: yet another approach to the MDI - Multi Document Interface.

The C++ Cmdline Library provides a framework for handling command line options and arguments.
Either variables (of any type) are set to values given at the command line. Or user defined functions are called with arguments (of any type) read from the command line.
It was developed and tested using kdevelop 2.1 and gcc 2.95.3 on SuSE Linux 7.3.
Main features:
- Easy extraction of command line arguments
- Automatic conversion of command line arguments to any type (even user defined classes)
- Convenient handling of command line usage errors by exceptions
- Complete documentation
- And all this is absolutely free

PHP Active Code Library (ACL) is a PHP 5 class used to store and call PHP files that are stored in a database.

The files are stored in a plain text field and not a binary field. PHP ACL also takes care of include/require calls.

If a file includes another file stored in the database, PHP ACL takes care of getting, generating, and including that file.

Easy Game Library is library of C++ classes designed to make game programming easier. Now it consists only of easy_sprite library which consists of classes for using sprites.

It should compile on different platforms because it uses SDL library as backend.

Installation:

To install run such sequence of commands:

make - Compiles library and tests

make install - Installs library and tests

GOBLIN is a C++ class library focussed on graph optimization and network programming problems. GOBLIN Graph Library deals with all of the standard graph optimization problems discussed by textbooks and in courses on combinatorial optimization.
This software package also consists of a shell interpreter which extends the well-known Tcl/Tk language to graph objects and a graph browser and editor tool. Executable solvers are available for practical optimization problems. The graph browser applies for teaching and scientific documentation purposes.
GOBLIN is open source software and licenced by the GNU Lesser Public License (LGPL). That is, GOBLIN may be downloaded, compiled and used for scientific, educational and other purposes free of charge. For details, in particular the statements about redistribution and changes of the source code, observe the LGPL document which is attached to the package.
Main features:
- The gosh interpreter extends the Tcl/Tk scripting language to graph objects in a natural way.
- The goblet graph browser and editor tool. Graphical front end to the library.
- An open class hierarchy which strictly separates between abstract classes (all mathematical algorithms are defined as methods of abstract classes), implementations (i.e. by incidence lists, adjacency matrices) and logical views (problem transformations).
- A generic branch and bound module with several applications to graph optimization.
- Logging and tracing functionality which allows to study the various algorithms by examples.
- A runtime configuration module controls the selection of mathemetical methods, logging information, and the tracing of data objects.
- Compile time configuration module for code optimization.
- A file interface which can be easily extended to new problem classes.
- Source code for executable solver programs.
Today, GOBLIN provides strongly polynomial algorithms for the following graph optimization problems:
- Shortest paths in graphs and digraphs with negative lengths.
- Negative cycles and minimum mean cycles.
- Strong and 2-connected components.
- Minimum spanning trees, arborescences and 1-trees.
- Maximum st-flows, feasible circulations and b-flows.
- Min-cost st-flows, b-flows and circulations.
- Assignment problems of any kind.
- 1-matchings, b-matchings, capacitated b-matchings, f-factors and degree-constrained subgraphs.
- Directed and undirected Chinese postman problems, T-joins.
Enhancements:
- This release comes with explicit code for orthogonal drawing of trees.
- There are also new generator methods for regular planara graphs.
- A lot of doxygen comments has been added, but dexcription are still far from complete.

The CentralNic Unicode Library provides some PHP classes for maniuplating Unicode data. These classes are general purpose but are intended for use when working with Internationalised Domain Names (IDNs).

Existing support for Unicode and multi-byte strings in PHP is not great, requiring either an extension that is not compiled into PHP by default, or one of a number of third-party libraries, most of which are not currently maintained (for example, the
I18N_UnicodeString class in PEAR was last updated in August 2004).

There is a Unicode extension under development, but it isnt public yet, and again requires a third party library to do the heavy lifting, so probably wont be enabled in a default PHP build.

Using the CentralNic Unicode Library is as simple as downloading the current release, and including the main Unicode.php file from your scripts. You then get instant access to the two Unicode_String and Unicode_Character classes.

The CentralNic Unicode Library is released under the GNU Library General Public License, version 2.0. This is not the "Lesser" GPL (version 2.1 and higher), which is more restrictive.

The use of the Library GPL means that you can use the code in your own proprietary software. While you are not obliged to pass back any changes you make to the code, we would greatly appreciate it if you did.
