+=head1 SYNOPSIS
+
+Spreadsheet interface to internal LON-CAPA data
+
+=head1 DESCRIPTION
+
+Lonspreadsheet provides course coordinators the ability to manage their
+students grades online. The students are able to view their own grades, but
+not the grades of their peers. The spreadsheet is highly customizable,
+offering the ability to use Perl code to manipulate data, as well as many
+built-in functions.
