Tags
Tags in SpacePro are used to combine and structure the resulting spaces.
Each space in a SpacePro program can be tagged with one tag from any number of tag groups. These tags are then used to structure the output of the space program in the "View" and "Read" pages and the overview chart on the Preface page.
You can create an arbitrary number of tag groups with an arbitrary amount of tags. The Generators 'stamp' the tags on to the spaces they generate.
