ccgfs is a transport-agnostic filesystem. Common transport modes are
"pull" and "push", the latter of which makes it possible to export a
filesystem located in a LAN to a DMZ host without needing to allow
connections from the DMZ as would be the case with the pull model.
Any transport can be used, e.g. ssh for encryption.

Turn English phrases to C or C++ declarations Cdecl is a program
which will turn English-like phrases such as "declare foo as array 5
of pointer to function returning int" into C declarations such as
"int (*foo[5])()". It can also translate the C into the
pseudo-English. And it handles typecasts, too. Plus C++. And in this
version it has command line editing and history with the GNU readline
library.

The compressed loopback device or cloop is a module for the Linux
kernel. It adds support for transparently decompressed, read-only
block devices. It is not a compressed file system in itself.

Coccinelle is a program matching and transformation engine which
provides the language SmPL (Semantic Patch Language) for specifying
desired matches and transformations in C code. Coccinelle was
initially targeted towards performing collateral evolutions in Linux.
Such evolutions comprise the changes that are needed in client code
in response to evolutions in library APIs, and may include
modifications such as renaming a function, adding a function argument
whose value is somehow context-dependent, and reorganizing a data
structure. Beyond collateral evolutions, Coccinelle is successfully
used (by us and others) for finding and fixing bugs in systems code.

The conntrack-tools are a set of tools targeted at system
administrators. They are conntrack, the userspace command line
interface, and conntrackd, the userspace daemon. The tool conntrack
provides a full featured interface that has replaced the old procfs
interface. Using conntrack, you can view and manage the in-kernel
connection tracking state table from userspace. On the other hand,
conntrackd covers the specific aspects of stateful firewalls to
enable highly available scenarios, and can be used as statistics
collector as well.

The Latin Modern fonts are derived from the famous Computer Modern fonts designed by Donald E. Knuth and first published by the American Matematical Society (AMS) in 1997. One of the main extensions is the
addition of an extensive set of diacritical characters, covering many scripts based on the Latin character set.

DeuTex is a wad composer for Doom, Heretic, Hexen and Strife. It can be used to extract the lumps of a wad and save them as individual files. Conversely, it can also build a wad from separate files. When extracting a lump to a file, it does not just copy the raw data, it converts it to an appropriate format (such as PPM for graphics, Sun audio for samples, etc.). Conversely, when it reads files for inclusion in pwads, it does the necessary conversions (for example, from PPM to Doom picture format). In addition, DeuTex has functions such as merging wads, etc. If you're doing any wad hacking beyond level editing, DeuTex is a must.

The Doomsday Engine is a source port with support for Doom, Heretic, and Hexen. It does not support BOOM extensions.

A firewalling tool to transparently filter network traffic passing a
bridge. The filtering possibilities are limited to link layer filtering
and some basic filtering on higher network layers. The ebtables tool
can be used together with the other Linux filtering tools, like
iptables. There are no incompatibility issues.

The elftoaout utility converts a static ELF binary to a static a.out
binary. If you are using an ELF system on a SPARC, you will need to
run elftoaout on the kernel image so that the SPARC PROM can boot the
image.

GAA is a code generator that turns GAA language expressions into C
code which then analyze the arguments and creates program help
descriptions.

GlusterFS is a clustered file-system capable of scaling to several
petabytes. It aggregates various storage bricks over Infiniband RDMA
or TCP/IP interconnect into one large parallel network file system.
GlusterFS is one of the most sophisticated file systems in terms of
features and extensibility. It borrows a powerful concept called
Translators from GNU Hurd kernel. Much of the code in GlusterFS is in
user space and easily manageable.
