Free beyond the red line demo software for linux

explosions demo project is a SDL-based toy with fireworks in 3D space and neat visual effects.

"Explosions" is a simple SDL-based demo written in C which displays a faux-3D environment with small sprites.

Using the mouse, you can cause little sparks (or fireworks) to appear. Using the keyboard, you can change the angle of viewing.

You can also toggle a number of nifty effects, like blur, fade, dissolve, rotation and zoom.

The C source-code is fully commented, and should be useful for learning some simple SDL and interesting effects code.

Red Carpet is a software management tool for RPM-based Linux distros.

Red Carpet is a suite of applications that allows easy installation and update of software on Linux systems. Red Carpet project features both command-line and graphical GNOME interfaces.

These days Red Carpet is part of the Novell ZenWorks solution.

etvis is a demo viewer/commenter for Wolfenstein: Enemy Territory FPS game.
Demos recorded with ET can be sorted, renamed, deleted, and viewed. Comments can be stored for each demo individually.
Comments will remain no matter if a demo-file gets renamed by etvis or by another application.
For now you have to edit some things by hand before compiling, this will be changed in a later release:
Edit src/main.h EXECPARAMS for options to give to ET
src/main.c line 174 for the dir that is filled with your demos
src/main.c line 184 for your ET executable
Usage:
double-click on the filename to rename it
delete-key to delete the selected demo files
double-click views the selected demo in ET
Enhancements:
- A demo file can now be given as a command line parameter to omit the GUI, which is nice for associating etvis with .dm_84 files in your favorite file manager.
- In addition, basic gettext functionality was added.

Tao Linux is a project to build a free Linux distribution from the sources used in the Red Hat Enterprise Linux product line.
The target market is either experienced system administrators who would like freely available binaries of this code, or end users who are interested in experimenting with enterprise functionality.
Besides being mostly compatible with Red Hat Enterprise Linux 3, it also includes software packages such as Eclipse and clustering tools not found in the base RHEL products.
Main features:
- Yum used for updates
- Based on commercially produced Enterprise sources
- Many packages for Red Hat Enterprise Linux also run on Tao Linux
- Free as in speech and beer
- Security updates (in SRPM form, at least) available for seven years.

The tecla library provides UNIX and LINUX programs with interactive command line editing facilities, similar to those of the unix tcsh shell. In addition to simple command-line editing, it supports recall of previously entered command lines, TAB completion of file names, and
in-line wild-card expansion of filenames.

The internal functions which perform file-name completion and wild-card expansion are also available externally for optional use by programs, along with a module for tab-completion and lookup of filenames in a list of directories.

Note that special care has been taken to allow the use of this library in threaded programs. The option to enable this is discussed in the Makefile, and specific discussions of thread safety are presented in the included man pages.

Installation:

To compile and optionally install the library, it is first necessary to create a makefile for your system, by typing:

./configure

The Makefile that this generates is designed to install the files of the library in subdirectories of /usr/local/. If you would prefer to install them under a different directory, you can type:

./configure --prefix /wherever

Where you would replace /wherever with your chosen directory. Other command-line options are available, and can be listed by typing:

./configure --help

Having run the configure script, you are then ready to make the library. To do this, just type:

make

What make does depends on whether the configure script knows about your system. If the configure script doesnt know anything specific about your system, it will arrange for make to produce the static tecla library, called libtecla.a, and if possible, the reentrant
version of this called libtecla_r.a. If it does know about your system, it will also create shared libraries if possible.

If you are on a system that isnt known, and you would like shared libraries to be compiled, please read the file called PORTING to see how this can
be achieved.

To install the library, its include file and it manual pages, type:

make install

Note that this will also compile the library if you havent already done so.

Having compiled the library, if you wish, you can test it by running the demo programs. After building the library, you should find two programs, called demo and demo2, in the current directory.

The first of the demos programs reads input lines from the user, and writes what was typed back to the screen. While typing a line of input, you can experiment with line editing, tab completion, history recall etc.

For details about these line editing features, see the man page gl_get_line(3). If you havent installed this yet, you can see it anyway by typing:

nroff -man man3/gl_get_line.3 | more

The second demo program, called demo2, demonstrates command-completion
with the UNIX PATH. If you type in a partial command name, and press TAB, the command name will be completed if possible, and possible completions will be listed if it is ambiguous.

When you then enter the line, the demo program then prints out the full pathname of the command that you typed. If you type anything after the command name, filename completion with the tab key reverts to its default behavior of completing filenames in the current directory.

Line Marker is an extension which adds a new menu "Line Marker" to the context menu.

It changes color of selection. Status of markers are saved to your profile.

Babylon Search Online Demo provides a Firefox toolbar for trying out Babylon dictionaries and Wikipedia via the Web.

Wikipedia search results are automatically shown as an easy-to-read summary, which is very convenient. Babylon is a multilingual Windows application (sold separately) from Israel.

It allows you to look up a word or term in multiple dictionary resources with just a single click.
