It included a `rpm2targz` +program. Slackware doesn't really have a dedicated project site for it since +it's part of the "base distro", so contributing changes back is difficult. + +Since unpacking RPMs w/out the `rpm` program is a generally useful function, +Gentoo imported & forked it decades ago, and has since maintained a number of +improvements & updates. Gentoo has opted to call the package `rpm2targz` to +help disambiguate and make it a little more clear that the focus is on generic +tar's rather than Slackware's tgz packages. It's unclear how many people +picked up on this nuance ;). + +Gentoo's `rpm2tgz` is specifically not compatible with Slackware's version. +Slackware's version is geared towards actually installing RPM's when your host +host distro is actually Slackware, while Gentoo's is meant to just be a generic +archive manipulation tool. Basically we consider the "tgz" to be a short name +for "tar.gz" rather than a package format by itself. + +The versioning has become desynced between the two projects. Since Slackware +just included it in the distro, Gentoo used the overall Slackware distro version +when importing. That's how we got: +* [rpm2targz-8.0.ebuild](https://gitweb.gentoo.org/repo/gentoo/historical.git/commit/?id=f4b34ca583b02f43962aa13fa7dc9384e2804cd8) +* [rpm2targz-9.0.ebuild](https://gitweb.gentoo.org/repo/gentoo/historical.git/commit/?id=8542b4a88931bd4fec2e29753ba3f014a19681ce) + +As the Gentoo version diverged from Slackware's, we added `.0.#g` to the end to +differentiate itself (with the "g" being short for "Gentoo"). Gentoo has now +moved on to the more common date-based version style since there's no point in +staying in sync anymore. + +## Slackware Readme + +* http://www.slackware.com/config/packages.php +* https://pkgs.org/download/rpm2tgz + +This package contains 'rpm2targz', a simple utility to convert Red Hat-style +RPM packages into standard tar.gz archives. Converted binary packages can then +be installed/removed using the 'installpkg/removepkg' commands, or 'pkgtool'. + +It's advisable to at least examine the converted package with 'less' to make +sure it won't do anything too crazy to your system. + +By default, rpm2targz will attempt to use "file" to detect source RPMS, and will +put the contents into a subdirectory in the resulting package. This may not be +portable to other operating systems -- if you're trying to run rpm2targz on an +OS that doesn't have a file that knows RPM types, and you care about this source +RPM feature, you can compile and install David Cantrell's standalone getrpmtype +utility.
