1013:
1014: This module publishes a directory of files.
1015:
1016: This is part of the LearningOnline Network with CAPA project
1017: described at http://www.lon-capa.org.

1042:
1043: =item startpage($r, $uame, $udom, $thisdisfn)
1044:
1045: Output the header of the page. This includes:
1046: - The HTML header
1047: - The H1/H3 stuff which includes the directory.
1048:
1049: startpage($r, $uame, $udom, $thisdisfn);
1050: $r - The apache request object.
1051: $uname - User name.
1052: $udom - Domain name the user is logged in under.
1053: $thisdisfn - Displayable version of the filename.
1054:
1055: =item getTitleString($fullname)
1056:
1057: Get the title string or "[untitled]" if the file has no title metadata:
1058: Without the latter substitution, it's impossible to examine metadata for
1059: untitled resources. Resources may be legitimately untitled, to prevent
1060: searches from locating them.
1061:
1062: $str = getTitleString($fullname);
1063: $fullname - Fully qualified filename to check.

1071: $reqfile - File in request.
1072: $here - Where we are in directory tree.
1073: $dirname - Name of directory special file.
1074: $modtime - Encoded modification time.
1075: targetdir - Publication target directory.
1076: bombs - Reference to hash of URLs with runtime error messages.
1077: numdir - Reference to scalar used to track number of sub-directories
1078: in directory (used in form name for each "actions" dropdown).
