Ditaa is a small command-line utility written in Java, that can convert
diagrams drawn using ascii art ('drawings' that contain characters that
resemble lines like | / - ), into proper bitmap graphics.

This reduces code duplication, but more importantly means that the
DRI modules can be found by X enabling hardware acceleration.
Close#249; the PR also refers to more about DRI modules.
Setfile is included by other derivation, which in turns makes them unfree, too.
This causes plenty of evaluation errors on Hydra, i.e.:
at `haskellPackages_ghc763_profiling.wx.x86_64-darwin' [nixpkgs = ..., officialRelease = false]:
user-thrown exception: package ‘setfile’ has an unfree license, refusing to evaluate
Now, it's true that "setfile" is unfree, but this doesn't affect us: our
derivation doesn't include the actual binary -- it just contains a symlink to
"/usr/bin/SetFile". Arguably, our setfile derivation is free and we can
re-distribute it.
Set "networking.tcpcrypt.enable = true;" to enable opportunistic TCP encryption
based on the user-space tools available from <http://tcpcrypt.org>.
Network attackers come in two varieties: passive and active (man-in-the-middle).
Passive attacks are much simpler to execute because they just require listening
on the network. Active attacks are much harder as they require listening and
modifying network traffic, often requiring very precise timing that can make
some attacks impractical.
Opportunistic encryption cannot protect against active attackers, but it *does*
protect against passive attackers. Furthermore, Tcpcrypt is powerful enough to
stop active attacks, too, if the application using it performs authentication.
A complete description of the protocol extension can be found at
<http://tools.ietf.org/html/draft-bittau-tcp-crypt-00>.
