TREK(6) 							 BSD Games Manual							   TREK(6)

NAME

     trek -- trekkie game

SYNOPSIS

     trek [-sf]

DESCRIPTION

     trek is a game of space glory and war.  Below is a summary of commands.  For complete documentation, see Trek by Eric Allman.

     The -s flag makes the game somewhat more efficient if you have a (very) slow terminal.  The -f flag (the default) is for faster terminals.

     The game will ask you what length game you would like.  Valid responses are ``short'', ``medium'', and ``long''.  You may also type
     ``restart'', which restarts a previously saved game.  You will then be prompted for the skill, to which you must respond ``novice'',
     ``fair'', ``good'', ``expert'', ``commodore'', or ``impossible''.	You should normally start out with a novice and work up.

     In general, throughout the game, if you forget what is appropriate the game will tell you what it expects if you just type in a question
     mark.
