So, here it is at last, the download.
The core source files are licenced under the Lesser GNU Public Licence. As far as we can tell, this means you can use it, but can't say you wrote it.
This source is at version 1.0. We're not expecting to find anything of a major problem with it, but we've only tested it in conjunction with a much larger library, so it is possible that calling it in other ways than those it expects will cause problems. Certainly if a problem is found, don't hesitate to contact us.
