914:
915: This module publishes a directory of files.
916:
917: This is part of the LearningOnline Network with CAPA project
918: described at http://www.lon-capa.org.
919:
920: =head1 HANDLER SUBROUTINE
921:
922: This routine is called by Apache and mod_perl.

924: =over 4
925:
926: =item *
927:
928: read in information
929:

931:
932: start page output
933:
934: =item *
935:
936: run through list of files and attempt to publish unhidden files

941:
942: =over
943:
944: =item startpage($r, $uame, $udom, $thisdisfn)
945:
946: Output the header of the page. This includes:
947: - The HTML header
948: - The H1/H3 stuff which includes the directory.
949:
950: startpage($r, $uame, $udom, $thisdisfn);
951: $r - The apache request object.
952: $uname - User name.
953: $udom - Domain name the user is logged in under.
954: $thisdisfn - Displayable version of the filename.
955:
956: =item getTitleString($fullname)
957:
958: Get the title string or "[untitled]" if the file has no title metadata:
959: Without the latter substitution, it's impossible to examine metadata for
960: untitled resources. Resources may be legitimately untitled, to prevent
961: searches from locating them.
962:
963: $str = getTitleString($fullname);
964: $fullname - Fully qualified filename to check.
