GNU enscript converts ASCII files to PostScript and stores generated output to a file or sends it directly to the printer. GNU enscript includes features for "pretty-printing" (language sensitive code highlighting) in several programming languages.

It supports ten different input encodings, Adobe Font Metrics files, and user defined fancy headers. AFM files for the most common PostScript fonts are included in the distribution; the program itself can download PostScript fonts.

Other features include language sensitive highlighting, N-up printing, inlined EPS images, comments, and the ability to change body color and font on the fly.

Supported Character Sets

Enscript supports following character sets:

- ISO-8859-1 ISO Latin1 (default)
- ISO-8859-2 ISO Latin2
- ISO-8859-3 ISO Latin3
- ISO-8859-4 ISO Latin4
- ISO-8859-5 ISO Cyrillic
- ISO-8859-7 ISO Greek
- ascii 7 bit ascii
- ascii fi se 7 bit ascii with following encodings:
{ = �(adieresis)
| = �(odieresis)
} = �(aring)
[ = �(Adieresis)

auch is a gnuplot-like program to visualize harmonics and test the effect of digital and analog filters.
This tool was originally made to see what the SoundBlaster X-FI soundcard can do. I wanted to...
- Compare original audio (.wav files) with processed audio and see the effect of EAX and SVM,...
- See the difference between MIDI - and real instruments.
Displays and settings:
auch has a simply concept. There are four displays:
- display :0 Audio from a .wav file (left channel)
- display :1 Audio from a .wav file (right channel)
- display :2 The microphone (or audio-in) (left channel)
- display :3 The microphone (id.) (right channel)
Enhancements:
- The rhythmic folding is a musical transformation based on reflection.
- If correctly tuned, it can mask off-beat notes.

Olive is (yet another) GNU/Linux Live distribution. Olive LiveCD distirbution offers quite a good deal of new technologies, hardly witnessed ever before, as well as some of the more common pieces of software. Its size is approx. 110MiB, yet it allows a lot of software to be used.
Olives whole point is to display how easy to use Linux may be, yet without losing any of the features required for heavy-duty work. Its also supposed to show various unusual new technologies, not widely known or accepted.
Please note that Olive was, partially, built as graduation work at SPSST Panska. Once presented, a release built specifically for school will be available upon personal request.
Main features:
Media
Olive features MPlayer for playing of your favourite movies. It plays most MPEG, VOB, AVI, OGG/OGM, VIVO, ASF/WMA/WMV, QT/MOV/MP4, FLI, RM, NuppelVideo, Matroska files. You can also watch Theora, MPEG4 (DivX/XviD), Real Media, DVD, VideoCD, SVCD movies. MPlayer also supports various filters for better experience. Mencoder is bundled with MPlayer and it allows you to encode movies into virtually any of the formats mentioned above.
Although you can use MPlayer to play your music, theres also an application that was written just for that: Audacious. Audacious is a fork of Beep Media Player (now discontinued), which is in turn fork of the very famous XMMS. It supports various audio formats, including MPEG layer 1, 2, and 3, Ogg Vorbis, Ogg FLAC, Musepack, WAV files and Windows Media, as well as many sequenced formats including MIDI, and a host of different module formats. In addition, Audacious uses Winamp-like skins (and supports Winamp "classic" skins), to provide a familiar and friendly user interface.
You can of course view photos and pictures using GQview, an intuitive image browser. It can generate thumbnails of your pictures, its capable of reading EXIF metadata, has advanced image search function and much more.
Internet
The Internet is part of everyday life for all of us; was it not for the Internet, you wouldnt be able to read this webpage. Olive features Mozilla Firefox web browser, currently the most common web browser used on Linux. For browsing in console, ELinks is a must-have. There is also Sylpheed e-mail client, small, fast and incredibly useful.
These days, Instant Messaging is a common part of our lives. Therefore, Olive sports GAIM2 (beta2) multi-protocol instant messaging client, which is compatibile with protocols such as ICQ, MSN Messenger,Yahoo!, IRC, Jabber or Gadu-Gadu. There is also a client dedicated solely to Internet Relay Chat (IRC), which is X-Chat. As usually, there are console alternatives, which would be CenterICQ and irssi.
You can use Kismet to look for Wi-Fi hotspots. Basic utilities such as telnet or ssh client and server (Dropbear, used in various embedded systems) are not missing as well.
General work
You can perform some elementary office work in Olive as well. Although its obvious that you wont be doing most of your office work on Olive, its quite reasonable to believe it can come in handy. Therefore, Olive has AbiWord word processor to allow you to read and write documents, in various languages, in various characters, without any problem.
AbiWord can also handle various document formats, which includes Microsoft Word or WordPerfect documents. You can also export your documents into HTML for further processing or publication. You can also read Adobe PDF format using Evince, a Gnome/GTK2 document viewer whose PDF backend is based on the Poppler library, which is based on the well-known XPDF. Utilities that allow you export of PDF documents into eg. HTML are also included.
System control
Considering the differences in approach to configuration in various distributions, it may be often hard to configure several things at yet another distribution, such as the X server or preferences of software alternatives. Therefore, Olive features a trivial control panel, allowing any application to be merged in as a new panel. Although it still misses few more desired panels (most notable for network configuration), it already is quite useful for every day usage.
Eye candy
Good-looking environment always helps users to better orientate on the workplace, as well as consider the time they spend with the system more enjoyable. Transparency can be achieved using XComposite extension and xcompmgr + transset.
Though XGL and AIGLX were considered, the decision was made not to use them for their lack of testing and for the demand for support of as many platforms as possible. Please note that even XComposite may have its own issues with other software, most notably Enlightenment and MPlayer, and for this reason xcompmgr is not run by default.
Lightweight
If you consider the above features way too much for you and strive for something lighter, then you can use the FluxBox window manager. FluxBox was finetuned to look and feel as much as Enlightenment as possible, making the transition simple. There are also lightweight versions of some of the software, as mentioned above, such as irssi, CenterICQ or ELinks.
Enhancements:
- A significant bug was found in v0.1, causing ramdisk for people who have 1GiB of RAM or more broken. Please, upgrade to 0.2.

IPTABLES masquerading firewall is a self contained script that enables and sets basic masquerading (assuming kernel kernel support already exists) at boot time. You may use this example, or modify existing init scripts to include the code.

Under Linux kernel 2.4.x, packet mangling has considerably changed. This includes the masquerading, firewalling, and port forwarding features. This document assumes youre using modules, if youre not, disregard the code in the following script that tests for the loaded module.

#!/bin/sh

# YOU MUST SET THE FOLLOWING THREE VARIABLES

# Set the full path to iptables
PROG=/path/to/iptables

# Set network interface to masquerade on. This will be the interface
# thats connected to the Internet. Possibilities include ppp0, eth0,
# eth1, etc.
IFACE=eth0

# Set machine or network to masquerade. This can be set as hostname, IP address,
# or network mask, examples:
# Hostname your_hostname
# IP address 192.168.1.2
# Net mask 192.168.1.0/24 This masquerades ALL machines on 192.168.1.x
INTNET=192.168.1.2

# Enable IP Masquerading in the kernel
echo 1 > /proc/sys/net/ipv4/ip_forward

# Test if iptable_nat module is loaded, its boot time, not likely :)
if [ -z "`lsmod|grep iptable_nat`" ];
then
modprobe iptable_nat
fi

# Test if existing MASQ rules exist, its boot time, not likely :)
if [ -z "`$PROG -L -t nat|grep MASQUERADE`" ];
then
$PROG -t nat -A POSTROUTING -o $IFACE -s $INTNET -j MASQUERADE
fi
