id3-writer

![ID3 Writer logo]()

ID3 Writer is a small and tested library for writing ID3 tags to MP3
files. We don't touch the files self - we speak to write adapters like
id3lib/libid3-tools or eyeD3. So this library is just a wrapper around the CLI programs.

I don't plan to support Windows explicit. But if someone requests a pull
for a write adapter with Windows support I will not reject it.


Features

* Support for multiple write adapters
* We check if some binaries are available to do the tasks
* eyeD3 (0.6.x, 0.7.x)
* id3lib/libid3-tools (3.8.x)
* Support for ID3v1 and ID3v2
* ID3v2 Tags need some validation at this point
* Support for converting the encoding of the given tags
* Support for writing images to the MP3 files (eyeD3 only atm)
