38: =head1 NAME
39:
40: Apache::loncfile - Construction space file management.
41:
42: =head1 SYNOPSIS
43:
44: Content handler for buttons on the top frame of the construction space
45: directory.
46:
47: =head1 INTRODUCTION
48:
49: loncfile is invoked when buttons in the top frame of the construction
1.17 harris41 50: space directory listing are clicked. All operations proceed in two phases.
1.12 foxr 51: The first phase describes to the user exactly what will be done. If the user
52: confirms the operation, the second phase commits the operation and indicates
53: completion. When the user dismisses the output of phase2, they are returned to
54: an "appropriate" directory listing in general.
55:
56: This is part of the LearningOnline Network with CAPA project
57: described at http://www.lon-capa.org.
