Given a pacman package (.pkg.tar.xz), is there a tool to convert it to a deb or rpm package?
In other words, I'm looking for an equivalent to alien. So far, I got the impression that such a tool does not exist.
Edit: Some background about .pkg.tar.xz pacman packages (source: Arch Wiki "Creating packages" article):
An Arch package is no more than a tar archive, or 'tarball', compressed using xz, which contains the following files generated by makepkg:
The binary files to install. .PKGINFO: contains all the metadata needed by pacman to deal with packages, dependencies, etc. .MTREE: contains hashes and timestamps of the files, which are included in the local database so that pacman can verify the integrity of the package. .INSTALL: an optional file used to execute commands after the install/upgrade/remove stage. (This file is present only if specified in the PKGBUILD.) .Changelog: an optional file kept by the package maintainer documenting the changes of the package. (It is not present in all packages.)
