Wikipedia:Articles for deletion/Alien (software)
There is a modest http://www.linuxjournal.com/content/alien-use-any-package-any-distribution Linux Journal article on the software and it pops up on commercial howto sites like http://www.howtogeek.com/howto/ubuntu/install-an-rpm-package-on-ubuntu-linux/ How-To Geek. Debian uses it to Linux Standard Base#Limitations on Debian|help improve conformance to the Linux Standard Base. http://www.tldp.org/LDP/www.debian.org/doc/manuals/debian-reference/ch11.en.html#_miscellaneous_data_conversion The Linux Documentation Project has an entry for the software. Joy and  Grandmartin11 have shown that there are thousands of GBook hits for the software. Between the LJ article, which I consider marginally in depth, some shorter articles on commercial howto sites and thousands of citations in books, I consider the software notable. In my opinion, in judging notability  allows for many small references in RS like books to substitute for an in-depth one: ''The number and nature of reliable sources needed varies depending on the depth of coverage and quality of the sources. Multiple sources are generally expected.'' There seems to be enough secondary material out there to support a modest article. With a notable topic and no major problems in the article, I recommend keeping the article
