[galaxy-dev] Shared Data as options for tools

Hi all, Is there a way, or better yet a coded example, of how to list the options for an input parameter using the contents of a shared data library? Up until now I've use Python scripts to get the input file options from a directory listing for a hardcoded path on the server, but it'd be much nicer to draw the list from a Shared Data folder, for maintenance and metadata purposes. Cheers, Paul
