+     "Structural equation modeling (SEM) has a long history of representing
+models graphically as path diagrams.  The semPlot package for R fills the gap
+between advanced, but time-consuming, graphical software and the limited
+graphics produced automatically by SEM software.  In addition, semPlot offers
+more functionality than drawing path diagrams: it can act as a common ground
+for importing SEM results into R.  Any result usable as input to semPlot can
+also be represented in any of the three popular SEM frame-works, as well as
+translated to input syntax for the R packages @code{sem} and @code{lavaan}.")
