I just finished cow package, and made some corrections to vanilla package.

Here are the three package descriptions:

Summary     : Netrek COW client
Description :
Netrek is the probably the first video game which can accurately be
described as a "sport."  It has more in common with basketball than
with arcade games or Quake.  Its vast and expanding array of tactics
and strategies allows for many different play styles; the best players
are the ones who think fastest, not necessarily the ones who twitch
most effectively.  It can be enjoyed as a twitch game, since the
dogfighting system is extremely robust, but the things that really set
Netrek apart from other video games are the team and strategic
aspects.  Team play is dynamic and varied, with roles constantly
changing as the game state changes.  Strategic play is explored in
organized league games; after 6+ years of league play, strategies are
still being invented and refined.

The game itself has existed for over 10 years, and has a solid
playerbase, including some people who have been playing for nearly as
long as the game has existed.

This is a client for the multi-player game of Netrek, supporting sound,
color bitmaps recording and playback of games.

This is a configuration program for the Netrek Vanilla Server.

Although the server will run out of the box, it can be configured to
behave differently through configuration files.  This program provides
a graphical interface to these files.  It is not required to play.
