Free consists of software for linux

Kernelcookies project consists of fortune cookies from the Linux Kernel.
Kernelcookies is a datafile for fortune that contains some of the funnier or more obscure kernel messages.
One of the most famous messages ("lp1 on fire") was part of the linuxcookies data file (and got me started on this compilation).
NOTE: Some of the cookies may contain offensive language. As I dont really want to decide on what someone might find offensive or not and create two seperate files, I only put this warning here. If you dont want offensive fortunes, youll have to weed this file out yourself.
Enhancements:
- 25 new cookies from Linux 2.6.19 were added.

Crossword Formatter consists of a script to easily format HTML crossword puzzles.
Crossword Fromatter is a simple script that generates valid XHTML code for static crossword puzzles from a simple definition file. The package also includes CSS files for proper display of the crossword puzzle.
With no arguments, the cwd.pl script reads a crossword definition file from standard input and writes an HTML version of the puzzle to standard output.
Enhancements:
- This release adds a Javascript solving interface and small bugfixes.

ndisc6 consists of two small command line tools (ndisc6 and rdisc6) that perform ICMPv6 Neighbor Discovery and ICMPv6 Router Discovery respectively.
NDisc6 is primarily meant for IPv6 networking diagnostics or to detect rogue IPv6 nodes or routers on an Ethernet segment.
Enhancements:
- traceroute has been parallelized for faster execution, and handles IPv6 extension headers and more ICMPv6 errors, UDP-Lite probes.
- rdisc6 supports RFC4191 (router preference and specific routes) and RDNSS.
