Tournament director, Peter Gallagher, the former Scotland age-grade and sevens coach/manager said: "The festival will take the form of a round-robin event. Some of the matches will be double-headers so there'll be something in it for everyone, no matter who you're supporting.
"And the chances are that supporters will get the first glimpse of some of the stars of the 2011 World Cup right here in Scotland."
