   Apache::lonupload - upload files into construction space
   
   =head1 SYNOPSIS

    <Location /adm/upload>
    PerlAccessHandler       Apache::lonacc
    SetHandler perl-script
    PerlHandler Apache::lonupload

   =head1 INTRODUCTION
   
   This module uploads a file sitting on a client computer into 
   library server construction space.
   
   This is part of the LearningOnline Network with CAPA project
   described at http://www.lon-capa.org.
   
   =head1 HANDLER SUBROUTINE
   
   This routine is called by Apache and mod_perl.
   
   =over 4
   
   =item *
   
   Initialize variables
   
   =item *
   
   Start page output
   
   =item *
   
   output relevant interface phase (phaseone or phasetwo or phasethree)
   
   =item *
   
   (phase one is to specify upload file; phase two is to handle conditions
   subsequent to specification--like overwriting an existing file; phase three
   is to handle processing of secondary uploads - of embedded objects in an
   html file).
   
   =back
   
   =head1 OTHER SUBROUTINES
   
   =over
   
   =item phaseone()
   
   Interface for specifying file to upload.
   
   =item phasetwo()
   
   Interface for handling post-conditions about uploading (such
   as overwriting an existing file).
   
   =item phasethree()
   
   Interface for handling secondary uploads of embedded objects
   in an html file.
   
   =item upfile_store()
   
   Store contents of uploaded file into temporary space.  Invoked
   by phaseone subroutine.
   
   =item check_extension()
   
   Checks if filename extension is permitted and checks type
    of file - if html file, calls parser to check for embedded objects.
    Invoked by phasetwo subroutine.
