How to install .deb packages on Fedora?

I come across some closed source software that only provides .deb packages. Fedora manages packages with rpm/yum. How to install the .deb packages on Fedora?

Alien is a tool to convert .deb package to .rpm package: http://joeyh.name/code/alien/

To download and install alien:

First download one package for alien from Debian FTP:

http://ftp.de.debian.org/debian/pool/main/a/alien/

$ tar xf alien-VERSION.tar.gz
$ cd alien
$ perl Makefile.PL; make; sudo make install

To convert a .deb package to a .rpm package:

$ alien -r package.deb

To install the converted rpm package:

$ sudo yum localinstall package.rpm
