File-Unpack

File::Unpack is an aggressive unpacker for archive files. We call it aggressive,
because it recursivly descends into any freshly unpacked file, if it appears to be an archive itself.
It also uncompresses files where needed. The ultimate goal of File::Unpack is
to extract as much readable text (ascii or any other encoding) as possible.
Most of the currently known archive file formats are supported.

While The following perl modules are considered helpful, although we may run
perfectly okay, if only a subset of these is available:

- File::LibMagic, File::MimeInfo::Magic
  File::LibMagic is preferred, its underlying libmagic is activly maintained.
   Its database is very large, and it is much faster than File::MimeInfo::Magic
   Beware, that File::MimeInfo::Magic may derive a mimetype from the suffix, if
   nothing else works.
- IO::Uncompress::AnyUncompress        (perl-IO-Compress)
- IO::Uncompress::AnyInflate
 - Compress::Raw::Bzip2
 - Compress::Raw::Zlib
- Archive::Zip
- String::ShellQuote

Do not use:
- File::MMagic, File::MMagic::XS, File::Type
  These three are inferior, compared to the other options.
- Archive::Tar
  It is pure perl, so it's a lot slower then your "/bin/tar"
  IT is heavy on memory, all will be read into memory.
- Archive::Zip
  If you are just going to be extracting zips (and/or other archives) you are
  recommended to look at using Archive::Extract
- "Archive::Extract"
  tries first to determine what type of archive you are passing it, by
  inspecting its suffix. It does not do this by using Mime magic.
  Maybe this module should use something like "File::Type" to determine the
  type, rather than blindly trust the suffix.
  Set $Archive::Extract::PREFER_BIN to 1, which will prefer the use of command
  line programs and won't consume so much memory. Default: use "Archive::Tar" -.




We also rely on a range of command line utilities to be callable via the shell.
