Think of tags as like a book index where you find words and which pages they are on, the same principle applies here. Although it's taken a stage further so it might not be the word, but the subject, so for example if you're looking for things to do with fractal gradients for example. A tag may bring back posts with gradient files, as well as posts that discuss gradients, or tutorials about them.

executed by any Java runtime and can be started with any options.
The task of the launcher is to launch the main software with controlled options
and to reserve enough memory.
