MP3::Tag.pm
===========
* It seems that to allow intelligent handling of Unicode file names we need to keep a non-decoded name (e.g., from readdir())
and a decoded one (to extract the info from the file name). Should not we expect that new() may be called with an unicode name???
What is below is not 100% clear now :-[
* perhaps restructuring of this wrapper module, as it
should be easier to say which Tag::modules should be used
Arguments in handlers
Direct handlers through __handler_read, __handler_write(). (To avoid security risks, writing-when-read-is-assumed etc.)
Possibly needed on ID3v1/ID3v2 only (others cannot write yet).
Take into account that title() etc take arguments (write!).
Be draconian when rejecting method calls; allow slack via config.
Allow Packages=*, pass through config.
Allow passing through field().
ID3v2::get_frame has wantarray(), but only in one place!
* more testing
MP3::Tag::ID3v1.pm
==================
* more testing
MP3::Tag::ID3v2.pm
==================
* Encryption of frames (read and write)
* Only first tag in front of file is read, tags inside mp3-data are ignored
* Following frames are only supported in RAW mode:
- EQUA -> Equalization
- ETCO -> Event timing codes
- MLLT -> MPEG location lookup table
- POSS -> Position synchronisation frame
- SYLT -> Synchronized tempo codes
- RVAD -> Relative volume adjustment
* more testing
* reading of frames is very strict following rules of ID3v2 definition, but
a lot of programs seem to do this not, so some frames are not read right
(eg TMED of contains 'DIG, MD' instead of '(DIG/MD)', but only
'(DIG/MD)' is returned correctly as 'Other Digital Media, MiniDisc'
'DIG, MD' is returned as 'DIG, MD'
* frames like TMED who have to be specially encoded, are doing this only
when the frame is read, not when it is written
* Support for v2.4 output (is input fully supported now?)
