a/rpm2tgz-1.2.2-x86_64-5.txz: Rebuilt. rpm2targz: when extracting the cpio archive from inside the RPM, use --no-absolute-filenames to protect against a poorly made RPM scribbling all over system files/directories. Thanks to Sl4ck3ver. Support -i option to ignore non-zero exit value from rpm2cpio. This allows repackaging some malformed RPMs. Thanks to ricky_cardo for the sample malformed RPM.
