function vers_conv($debvers) {
        preg_match("/(.+:)?([^-]+)(ds|dsfg|debian)/",$debvers,$matches);
        if (!$matches[3]) {
                unset($matches);
                preg_match("/(.+:)?([^-]+)/",$debvers,$matches);
        }
        if (substr($matches[2],-1)=='.') $matches[2]=substr($matches[2],0,-1);
        return $matches[2];
}
