Smugup creates a new album with the given title if one does not already exist.
Then uploads the list of images to the album. If a particular image
already exists in the album, the JPG replaces the album image if the
contents differ.
Smugup fetches the SmugMug user name and password from the
user's keychain.
By default, new albums are created as private as possible: not public,
not world searchable, and not SmugMug-searchable.
Smugup prints the URL for the album when finished.
The options are:
-u user
SmugMug user account name (email address).
This is not typically needed, as the user name found in the keychain will be used.
