   =head1 NAME
   
   Apache::loncfile - Construction space file management.
   
   =head1 SYNOPSIS
    
    Content handler for buttons on the top frame of the construction space 
   directory.
   
   =head1 INTRODUCTION
   
     loncfile is invoked when buttons in the top frame of the construction 
   space directory listing are clicked.   All operations procede in two phases.
   The first phase describes to the user exactly what will be done.  If the user
   confirms the operation, the second phase commits the operation and indicates
   completion.  When the user dismisses the output of phase2, they are returned to
   an "appropriate" directory listing in general.
   
       This is part of the LearningOnline Network with CAPA project
   described at http://www.lon-capa.org.
