+     "@code{exceltex} is a LaTeX package combined with a helper program
+written in Perl.  It provides an easy to use yet powerful and flexible way to
+get data from spreadsheets into LaTeX. In contrast to other solutions,
+@code{exceltex} does not seek to make the creation of tables in LaTeX easier,
+but to get data from spreadsheets into LaTeX as easily as possible.  The Excel
+file format only acts as an interface between the spreadsheet application and
+@code{exceltex} beacause it is easily accessible (via the
+@code{Spreadsheet::ParseExcel} Perl module) and because most spreadsheet
+applications are able to read and write Excel files.")
