- * This thumbnail caching implementation attempts to conform

- * The standard is documented here:
- * http://triq.net/~jens/thumbnail-spec/index.html
- * (why isn't it actually hosted on freedesktop.org?)
- *
- * This code attempts to conform to version 0.7.0 of the standard.
- *
- * Notes:
- * > Validation of the thumb's embedded uri is a simple strcmp between our
- * version of the escaped uri and the thumb's escaped uri. But not all uri
- * escape functions escape the same set of chars, comparing the unescaped
- * versions may be more accurate.
- * > Only Thumb::URI and Thumb::MTime are stored in a thumb at this time.
- * Storing the Size, Width, Height should probably be implemented.
