+ (description
+ "This package provides a general purpose toolbox for personality,
+psychometric theory and experimental psychology. Functions are primarily for
+multivariate analysis and scale construction using factor analysis, principal
+component analysis, cluster analysis and reliability analysis, although others
+provide basic descriptive statistics. Item Response Theory is done using
+factor analysis of tetrachoric and polychoric correlations. Functions for
+analyzing data at multiple levels include within and between group statistics,
+including correlations and factor analysis. Functions for simulating and
+testing particular item and test structures are included. Several functions
+serve as a useful front end for structural equation modeling. Graphical
+displays of path diagrams, factor analysis and structural equation models are
+created using basic graphics.")
