Used alone, it displays the existing access permissions. The -del flag will allow the user to choose which permission sets to delete. Older versions of the software were not too friendly in handling symlinks. This has changed, and now symlinks will be archived without any special handling. The symlink itself will be archived rather than the file it links to.
Script tries to be smart and tacks on trailing slash to directories if needed.
If the user has an existing file or directory with the same name as one of the opposite type in the archive, retrieve, query and delete may act strangely. The dsm software never returns.
