35: =head1 SYNOPSIS
36:
37: Spreadsheet interface to internal LON-CAPA data
38:
39: =head1 DESCRIPTION
40:
41: Lonspreadsheet provides course coordinators the ability to manage their
42: students grades online. The students are able to view their own grades, but
43: not the grades of their peers. The spreadsheet is highly customizable,
44: offering the ability to use Perl code to manipulate data, as well as many
45: built-in functions.
