Apart from being used by myself as the software that drives my personal blog,
it is also a useful showcase for various TG programming patterns.
The software is currently in alpha state, because the data model and the API
(internal and external, i.e. URls) may still change frequently and some
features I consider important are still missing. That being said, I already use
it on a regular basis for my own blog site.
