                     43:  
                     44:  Content handler for buttons on the top frame of the construction space

                     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:
