45: =head1 SYNOPSIS
46:
47: Spreadsheet interface to internal LON-CAPA data
48:
49: =head1 DESCRIPTION
50:
51: Lonspreadsheet provides course coordinators the ability to manage their
52: students grades online. The students are able to view their own grades, but
53: not the grades of their peers. The spreadsheet is highly customizable,
54: offering the ability to use Perl code to manipulate data, as well as many
55: built-in functions.
