Can I freely use Sword in my projects ?

Yes, you can. Sword is released under the terms of the GNU Lesser Public License, which means you can use it without restrictions in your projects (whether they are Open Source or not). The only requirement is that you keep the copyright notices on all the files, and that if you give out the library to someone else, you must give all the sources and copyright information with it.

As usual with Open Source, we would appreciate if you contribute back any changes (fixes, improvements...) that you make to the library. Also if you use Sword in big commercial projects, we would appreciate some funds to support the developement. On demand, we can also study consulting to help you work with Sword.

How stable is Sword ?

You should'nt be afraid by the "beta 0.2.x" version number. All features documented in the manual are stable and production-ready. The library is used every day in several critical application in a demanding production environment.

The undocumented features are not yet stable, either because their interface will change or because they are not tested enough. When all interfaces are stables and enough testing has been made, Sword will mature in version 1.0.0.

What are the technical requirements ?

Your software, if using Sword will also have to rely on ACE. ACE is a very impressive piece of software which gives you many portable concurrency and networking classes and patterns. There was no way we could have done a better job, so we decided to use ACE as an environment abstraction layer and to complement with higher level or other missing features.

If you want to use GUI classes from Sword, you will have to rely on QT as well. QT is a portable GUI toolkit which comes for free on Unix and MacOSX, and can be bought at a reasonable price on Windows.

Otherwise, you will need a working C++ compiler (GCC 3.2 or better, Microsoft Visual Studio 6 or better) and we support Unix (GNU/Linux and Solaris are tested), MacOSX and Microsoft environments (Windows 2000 is tested).
