minitar 0.6

The minitar library is a pure-Ruby library that provides the ability to deal with POSIX tar(1) archive files. This is release 0.6, providing a number of bug fixes including a directory traversal vulnerability, CVE-2016-10173. This release starts the migration and modernization of the code: * the licence has been changed to match the modern Ruby licensing scheme (Ruby and Simplified BSD instead of Ruby and GNU GPL); * the +minitar+ command-line program has been separated into the +minitar-cli+ gem; and * the +archive-tar-minitar+ gem now points to the +minitar+ and +minitar-cli+ gems and discourages its installation. Some of these changes may break existing programs that depend on the internal structure of the minitar library, but every effort has been made to ensure compatibility; inasmuch as is possible, this compatibility will be maintained through the release of minitar 1.0 (which will have strong breaking changes). minitar (previously called Archive::Tar::Minitar) is based heavily on code originally written by Mauricio Julio Fernández Pradier for the rpa-base project.
