60: =head1 NAME
61:
62: Apache::loncfile - Construction space file management.
63:
64: =head1 SYNOPSIS
65:
66: Content handler for buttons on the top frame of the construction space
67: directory.
68:
69: =head1 INTRODUCTION
70:
71: loncfile is invoked when buttons in the top frame of the construction
1.17 ! harris41 72: space directory listing are clicked. All operations proceed in two phases.
1.12 foxr 73: The first phase describes to the user exactly what will be done. If the user
74: confirms the operation, the second phase commits the operation and indicates
75: completion. When the user dismisses the output of phase2, they are returned to
76: an "appropriate" directory listing in general.
77:
78: This is part of the LearningOnline Network with CAPA project
79: described at http://www.lon-capa.org.
