I'm missing the following packages in Guix.  If no one has planned to
package them yet, I'll give it a go.

fortune: 	The Fortune Cookie Program from BSD games
Upstream URL: 	http://www.shlomifish.org/open-source/projects/fortune-mod/

gifsicle: 	A powerful command-line program for creating, editing, manipulating and getting information about GIF images and animations
Upstream URL: 	http://www.lcdf.org/gifsicle/

inxi: 	script to get system information
Upstream URL: 	https://github.com/smxi/inxi

uncrustify: 	A source code beautifier
Upstream URL: 	http://uncrustify.sourceforge.net/

Description: 	The RAR uncompression program
Upstream URL: 	http://www.rarlab.com/rar_add.htm
(Not sure about the licensing of this one: does not look free.  Is there
any free way to extract RAR?)

vsftp: 	Very Secure FTP daemon
Upstream URL: 	https://security.appspot.com/vsftpd.html
(It seems that there is not a single FTP server on Guix.  Strange... Can anyone
recommend anything better than vsftp for file sharing?  Not necessarily
FTP.)

xss-lock: 	Use external locker as X screen saver
Upstream URL: 	https://bitbucket.org/raymonad/xss-lock
