I have been working on DirectoryTestScriptL, which will be able to deal with multiple OPML files. My design for this update includes three new functions:
ImportDirectoryFiles - open the OPML files and import them as outlines in the workspace table
CreateTopLevelPage - make the index page with a list of the OPML directory names
CreateDirectories - Call the previous rendering code for each directory
Completed the ImportDirectoryFiles function today - was able to import two OPML files.
