In more details: It allows the creation of gzip, bzip2, tar and zip files through a single API. There's a registry of supported formats and the API is driven by a format identifier.

Will it also allow decompression of the said archive types? Distribute has some utility code to handle zip/tar archives. So does PyPM. This is because the tarfile and zipfile modules do not "just work" due to several issues.

See http://gist.github.com/279606

Take note of the following in the above code:

  1. _ensure_read_write_access
  2. *File.is_valid
  3. ZippedFile.extract ... issue 6510
  4. ZippedFile.extract ... issue 6609
  5. TarredFile.extract ... issue 6584
  6. The way unpack() detects the unpacked directory.
