+The <link linkend="ai-equinox">Equinoxes</link> and 
+Solstices module calculates the date and time of an 
+equinox or solstice for a given year.  You specify which 
+event (Spring Equinox, Summer Solstice, Autumn Equinox, 
+or Winter Solstice) should be investigated, and the year.  
+Then press the <guibutton>Compute</guibutton> button to 
+obtain the date and time of the event, and the length of 
+the corresponding season, in days.
+</para>
+<para>
+There is a batch mode for this module.  To use it, simply 
+generate an input file whose lines each contain a year 
+for which the Equinox and Solstice data will be computed.  
+Then specify the input and output filenames, and press the 
+<guibutton>Run</guibutton> button to generate the output 
+file.  Each line in the output file contains the input year, 
+the date and time of each event, and the length of each 
+season.
