Pantheios is an Open Source C/C++ Logging API library, offering an optimal combination of 100% type-safety, efficiency, genericity and extensibility. It is simple to use and extend, highly-portable (platform and compiler-independent) and, best of all, it upholds the C tradition of you only pay for what you use.
The project supports logging of message statements of arbitrary complexity, consisting of heterogenous types.
Pantheios supports filtering of log messages based on severity level including (but not limited to) the eight levels defined by the SysLog protocol.
Pantheios supports back-end output, individually and in combination, to stderr/stdout, SysLog (including a custom implementation of the SysLog protocol for Windows), Win32 debugger, Win32 event log, COM Error Object, or any custom back-end extension you care to write. Importantly, Pantheios is readily extended to use the existing transport mechanisms of feature-rich logging libraries such as ACE, log4cpp, log4cplus, log4cxx.
Pantheios does not contain any compiler-specific or platform-specific constructs. It supports UNIX (including Linux and Mac OS-X), and Windows, and should work with any operating system. It is known to be compatible with Borland (5.5.1+), Comeau (4.3.3+), Digital Mars (8.45+), GCC (3.2+), Intel (6+), Metrowerks (8+), Microsoft Visual C++ (5.0+), and should work with any reasonably modern C++ compiler.
Pantheios is completely free and includes source released under a BSD-style licence.
Pantheios was forked from a previous logging architecture, proprietary to Synesis Software, in 2005, and has been used in a number of commercial projects since that time. In one project it serves a middleware suite that handles 10s of millions of financial transactions per week, wherein it has an unmeasurably low impact on performance when logging (of a given severity level) is switched off. (Its also decidedly quick with logging switched on, of course ...).
Enhancements:
- A bug in the Pantheios Tracing API was fixed.
- An example for the Pantheios Tracing API was added.
- A variadic macro warning in GCC 3.x makefiles was suppressed.

PRES project (the Press Release System) is a simple content management system, essentially targeted at producing a news and information site. Managing a PRES system is designed to be simple.
However, presentation is sophisticated and flexible. An elementary knowledge of IT would be useful but expertise in designing and managing websites is not a requirement. PRES can be used for anything from private blogging to corporate news systems.
Main features:
Flexible Presentation
- All content is generated as XML which is styled at server side with XSL-T stylesheets to provide the final look and feel of your pages. This permits an almost infinite variety of presentations. Furthermore, different XSL-T transforms can be associated with different categories, allowing you to have different styling for different parts of your site.
Caching
- Content is generated on request, but in order to limit the computational load on busy sites all content is cached for a limited period (by default twenty minutes).
Subscription
- PRES allows users to subscribe to categories - effectively sections of the site. When new stories are posted to a section youre subscribed to, you will automatically get email with a link to the story.
Syndication
- PRES makes its headlines available as a syndication feed, using both RSS 0.91 and RSS 1.0. This allows other news sites to automatically incorporate live headlines from a PRES site into their content.
Threaded Discussion
- PRES optionally allows registered users to add comments to stories in a threaded manner, similar to sites like Slashdot.
Moderation
- PRES optionally allows registered users to moderate other users comments.
