Liquid Pro is the fully documented version of the popular freeware
Liquid.
- Using XML to describe applications (presentations/animations/games) as Liquid does, means that they are safely deployed over the internet while also runnable as desktop applications.
Being XML, they are also easy to update or edit.
The language itself is easy to learn to handcode, for example in notepad, especially so for anyone accustom to HTML, which is another strong advantage.

XML is the future for applications as well, and Liquid is the first one out.
