- Add support for different camera filename formats, check with the Olympus.

- First, I think I'd like to see the PARENTDIR argument become a named switch (-d --parent-dir), to better differentiate it from the list of files to be processed.

- Second, I'd like to start using a config file (~/.photoname) that will contain things like default parent dir:
   parent-dir=/foo/bar/baz

   This would be used in the event that none was specified. Other switches could be specified here perhaps.

   This config file behavior will require a config file API, I can try to use the one I started a few months ago.

- I'm wondering if it would be possible to have a post-command switch that could specify something to be done after other processing is done. This came up when i was thinking about rolling jhead -autorot rotation behavior into this program. But I'm reluctant to make this program have direct knowledge of such tools and procedures.
   An example:
   --post-cmd='jhead -autorot %f'

   What syntax to use for variables in such strings?

- Allow user to specify permissions for newly-created dirs and files. Bonus points for parsing the octal codes everyone knows and loves.

- Add a --force switch to disregard existing links.

- Deal gracefully with unknown dates. This means not just putting pictures into the 0000/0000-00-00 directory, but making sure that the _### serial number part is incremented from the highest one in there.

- Allow additional switch for part of filenames for initials of photographer: _xyz  Call this the suffix? (-s --suffix)

- Add the Homepage item to the debian/control that you see now in more recent packages. Use dh_make on something to see what it looks like, something like this:
   Homepage: <url>
