+=head1 NAME
+
+Apache::lonupload - upload files into construction space
+
+=head1 SYNOPSIS
+
+Invoked by /etc/httpd/conf/srm.conf:
+
+ <Location /adm/upload>
+ PerlAccessHandler Apache::lonacc
+ SetHandler perl-script
+ PerlHandler Apache::lonupload
+ ErrorDocument 403 /adm/login
+ ErrorDocument 404 /adm/notfound.html
+ ErrorDocument 406 /adm/unauthorized.html
+ ErrorDocument 500 /adm/errorhandler
+ </Location>
+
+=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, phasetwo, phasethree or phasefour)
+
+=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 phasefour()
+
+Interface for handling optional renaming of links to embedded
+objects.
+
+=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.
