+=head1 INTRODUCTION
+
+This module uploads a file sitting on a client computer into
+library server construction space.
+
+This is part of the LearningOnline Network with CAPA project
+described at http://www.lon-capa.org.

+
+=item *
+
+(phase one is to specify upload file; phase two is to handle conditions
+subsequent to specification--like overwriting an existing file; phase three
+is to handle processing of secondary uploads - of embedded objects in an
