	lonspreadsheet

	=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.
