conquest-gl package information
a real-time, multi-player space warfare game (OpenGL client)
Conquest is a predecessor of netrek. The object of the game is twofold. The short-range goal is to accumulate "kills" by shooting down enemy players. You get one kill point for each enemy ship shot down, plus some extra if the enemy had kills too. The major weapon used to shoot down ships is the photon torpedo. The long-range goal is to conquer the universe for your team by taking every planet. You take planets by killing off the enemy's armies via bombardment, and then beaming your team's armies down. When all the planets have been taken, the game ends, a new game begins, and the player who actually took the last planet gets his/her name up in lights. This package contains the OpenGL client.
More information about apt-get remove
Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.
apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library.
apt-get remove is identical to install except that packages are removed instead of installed. Note that removing a package leaves its configuration files on the system. If a plus sign is appended to the package name (with no intervening space), the identified package will be installed instead of removed.
