Photoshop Tags
Photoshop tags are found in PSD files, as well as inside embedded Photoshop
information in many other file types (JPEG, TIFF, PDF, PNG to name a few).
Many Photoshop tags are marked as Unknown (indicated by a question mark
after the tag name) because the information they provide is not very useful
under normal circumstances (and because Adobe denied my application for
their file format documentation -- apparently open source software is too
big a concept for them).  These unknown tags are not extracted unless the
Unknown (-u) option is used.
