+=head1 NAME
+
+Apache::edit - edit mode helpers
+
+=head1 SYNOPSIS
+
+Invoked by many homework and xml related modules.
+
+ &Apache::edit::SUBROUTINENAME(ARGUMENTS);
+
+=head1 INTRODUCTION
+
+This module outputs HTML syntax helpful for the rendering of edit
+mode interfaces.
+
+This is part of the LearningOnline Network with CAPA project
+described at http://www.lon-capa.org.
+
+=head1 HANDLER SUBROUTINE
+
+There is no handler subroutine.
+
+=head1 OTHER SUBROUTINES
