 \title{The spatstat.linnet Package}
 \description{
-  The \pkg{spatstat.linnet} package is a subset of the
-  \pkg{spatstat} package containing the functionality
-  for spatial data on a linear network.
+  The \pkg{spatstat.linnet} package
+  belongs to the \pkg{spatstat} family of packages.
+  It contains the functionality
+  for analysing spatial data on a linear network.

+  a family of \R packages
+  for the statistical analysis of spatial data.
+  Its main focus is the analysis of
   spatial patterns of points in two-dimensional space.
 
-  The orginal \pkg{spatstat} package has grown to be very large.
-  It is now in the process of being divided into several

+  The original \pkg{spatstat} package
+  has now been split into several
+  sub-packages.
+
 
   This sub-package \pkg{spatstat.linnet} contains the
   user-level functions from \pkg{spatstat} 
   that are concerned with spatial data on a linear network.

-  (Most of the remaining functionality is 
-  in the separate sub-package \pkg{spatstat.core}.)

+\section{Structure of the spatstat family}{  
+  The orginal \pkg{spatstat} package grew to be very large.
+  It has now been divided into several \bold{sub-packages}:
+  \itemize{
+    \item \pkg{spatstat.utils} containing basic utilities
+    \item \pkg{spatstat.sparse} containing linear algebra utilities
+    \item \pkg{spatstat.data} containing datasets
+    \item \pkg{spatstat.geom} containing geometrical objects
+    and geometrical operations
+    \item \pkg{spatstat.core} containing the main functionality
+    for statistical analysis and modelling of spatial data
+    \item \pkg{spatstat.linnet} containing functions for
+    spatial data on a linear network
+    \item \pkg{spatstat}, which simply loads the other sub-packages
+    listed above, and provides documentation.
+  }
+  When you install \pkg{spatstat}, these sub-packages are also
+  installed. Then if you load the \pkg{spatstat} package by typing
+  \code{library(spatstat)}, the other sub-packages listed above will
+  automatically be loaded or imported.
+  For an overview of all the functions available in these sub-packages,
+  see the help file for \pkg{spatstat} in the \pkg{spatstat} package,
+
+  Additionally there are several \bold{extension packages:}
+  \itemize{
+    \item \pkg{spatstat.gui} for interactive graphics
+    \item \pkg{spatstat.local} for local likelihood
+    (including geographically weighted regression)
+    \item \pkg{spatstat.Knet} for additional, computationally efficient code
+    for linear networks
+    \item \pkg{spatstat.sphere} (under development) for spatial data
+    on a sphere, including spatial data on the earth's surface
+  }
+  The extension packages must be installed separately
+  and loaded explicitly if needed. They also have separate documentation.
