Archive-tar-external

This can be used as a addon to the classical TAR compressing packages.

What is new in this release:

• The create_archive method now accepts an optional second argument that specifies options to the tar command. The default is 'cf' (create file).
• The gem:create task was updated for Rubygems 2.x.
• Added rake as a development dependency.
• Ruby 1.8.x support has been dropped. This only matters for MS Windows.

What is new in version 1.2.3:

• Fixed a packaging bug.
• Added cygwin and mingw to Windows checks.
• Now requires open3 properly for Ruby 1.9 on Windows.
• Minor modifications to the gemspec.
• Added the 'gem' rake task.

Requirements:

• Ruby 1.8.0 or higher
• The win32-open3 package (MS Windows only)
• The "tar" command line program
• At least one compression program, e.g. gzip, bzip2, zip, etc.
