48: =head1 INTRODUCTION
49:
50: This module uploads a file sitting on a client computer into
51: library server construction space.
52:
53: This is part of the LearningOnline Network with CAPA project
54: described at http://www.lon-capa.org.

56: =head1 HANDLER SUBROUTINE

60: =over 4
61:
62: =item *
63:
64: Initialize variables
65:
66: =item *
67:

1.39 jms 73:
74: =item *
75:
76: (phase one is to specify upload file; phase two is to handle conditions
77: subsequent to specification--like overwriting an existing file; phase three
78: is to handle processing of secondary uploads - of embedded objects in an
79: html file).
