From the developer:
The purpose of this program is to facilitate the statistical analysis of landmark data in morphometrics. It is used to explore the relationships between variation in shape and either another shape or a set of variables. While related, its use differs from regression in that the variables and the shapes are treated equally rather than trying to explain variation in shape as a function of variation in a set of independent variables.
