+.TH MAELSTROM "6" "April 2009" "Ambrosia Software" "Games"
+.SH NAME
+Maelstrom \- Enhanced Asteroids\-like game
+.SH SYNOPSIS
+.B Maelstrom
+[\-netscores] \-printscores
+.P
+.B Maelstrom
+[options]
+.P
+.B Maelstrom\-netd
+.br
+\fI(see NETWORKING, below, for a description of Maelstrom\-netd)\fR
+.SH DESCRIPTION
+Maelstrom is a game based on Asteroids, but with several gameplay enhancements:
+.P
+\- High\-resolution color graphics
+.br
+\- Digital audio
+.br
+\- Powerups
+.br
+\- Networked multiplayer/deathmatch mode (up to 3 players)
+.br
+\- World\-wide high score server
+.P
+Game storyline:
+.br
+You pilot your ship through the dreaded "Maelstrom" asteroid belt \-\-
+suddenly your best friend thrusts towards you and fires, directly at your
+cockpit. You raise your shields just in time, and the battle is joined.
+.P
+The deadliest stretch of space known to mankind has just gotten
+deadlier. Everywhere massive asteroids jostle for a chance to crush your
+ship, and deadly shinobi fighter patrols pursue you across the asteroid
+belt. But the deadliest of them all is your sister ship, assigned to
+you on patrol. The pilot, trained by your own Navy, battle hardened by
+months in the Maelstrom, is equipped with a twin of your own ship and
+intimate knowledge of your tactics.
+.P
+The lovely Stratocaster R&R facility never sounded so good, but as you
+fire full thrusters to dodge the latest barrage you begin to think you'll
+never get home...
+.SH OPTIONS
+.TP
+\fB\-fullscreen\fR
+Run Maelstrom in full\-screen mode. You may also press Alt\-Enter
+while Maelstrom is running, to toggle full\-screen.
+.TP
+\fB\-gamma\fR [0\-8]
+Set the gamma correction
+.TP
+\fB\-volume\fR [0\-8]
+Set the sound volume
+.TP
+\fB\-netscores\fR
+Use the world\-wide network score server
+.TP
+\fB\-player\fR N[@host][:port]
+Designate player N (at host and/or port). N must be an integer, 1 to 3.
+.TP
+\fB\-server\fR N@host[:port]
+Play with N players using server at host. N must be an integer, 1 to 3.
+.TP
+\fB\-deathmatch\fR [N]
+Play deathmatch to N frags (default = 8)
+.SH CONTROLS
+The game may be played with either the keyboard or a joystick.
+The game controls may be remapped by pressing C at the main menu. The
+default keyboard controls are:
+.TP
+\fBTab\fR, \fBJoystick Button 1\fR
+Fire
+.TP
+\fBUp Arrow\fR, \fBJoystick Up\fR
+Thrust
+.TP
+\fBSpace\fR, \fBJoystick Button 2\fR
+Shield
+.TP
+\fBRight Arrow\fR, \fBJoystick Right\fR
+Turn Clockwise
+.TP
+\fBLeft Arrow\fR, \fBJoystick Left\fR
+Turn Counter\-clockwise
+.TP
+\fBP\fR
+Pause
+.TP
+\fBEscape\fR
+Abort Game
+.TP
+\fBAlt\-Enter\fR
+Toggle between fullscreen and windowed modes. This keystroke
+may not be remapped.
+.P
+No special configuration must be done to play with a joystick, provided
+the joystick is supported by the SDL library on your OS.
+There is no way
+to remap the joystick controls.
+.SH NETWORKING
+.SS Netplay Without a Server
+Networking has been tested on Linux, SGI and DEC.  It is known to
+work between SGI and DEC systems (cross\-platform), and between systems
+of the same type.
+.P
+Up to three players can play, and the syntax is as follows:
+.P
+(On machine 1)
+.br
+.B
+.nh
+Maelstrom \-player 1 \-player 2@machine2 \-player 3@machine3
+.hy
+.P
+(On machine 2)
+.br
+.B
+.nh
+Maelstrom \-player 1@machine1 \-player 2 \-player 3@machine3
+.hy
+.P
+(On machine 3)
+.br
+.B
+.nh
+Maelstrom \-player 1@machine1 \-player 2@machine2 \-player 3
+.hy
+.SS Netplay With a Server
+You can also use a network address server that handles the difficulties
+of getting all the players and addresses right.  The address server is
+installed as \fBMaelstrom\-netd\fR, and if run on say "servhost", the syntax
+for a three player game would be:
+.P
+(On machine A)
+.br
+.B
+.nh
+Maelstrom \-player 1 \-server 3@servhost
+.hy
+.P
+(On machine B)
+.br
+.B
+.nh
+Maelstrom \-player 2 \-server 3@servhost
+.hy
+.P
+(On machine C)
+.br
+.B
+.nh
+Maelstrom \-player 3 \-server 3@servhost
+.hy
+.P
+The address server will let players know if they have conflicting
+player numbers, and will set up the proper addresses for all players.
+It can field multiple games, and can be a "game hub" where a bunch
+of players can get together for romping network games. :)
+.P
+\fBNOTE\fR: Maelstrom-netd will not run correctly on 64\-bit hosts,
+and Maelstrom running on a 64\-bit host cannot successfully play in a
+mutiplayer game with the -server option. Use non\-server networked
+play mode instead.
+.SS Network Ports
+By default, Maelstrom uses UDP ports 44718 to 44720 for networked games,
+where the port number is the player number plus 44717.
+(these may be overridden with the \fI:port\fR syntax, above).
+.P
+\fBMaelstrom-netd\fR listens on TCP port 44717.
+.P
+The global
+high\-score server listens on the host \fBdevolution.com\fR, TCP port 4444.
+.SH ADD\-ONS
+Maelstrom add\-ons consist of replacement sounds, replacement sprites,
+or both. Typically, the add\-on content is distributed as a zip file.
+.P
+There is a collection of Maelstrom add\-on content at
+.br
+.nh
+\fIhttp://www.devolution.com/~slouken/Maelstrom/add-ons.html\fR
+.hy
+.SS Automated Installation (Preferred)
+Use \fBmaelstrom_addon_package.pl\fR to convert the zip
+file to a Slackware package, then use \fBinstallpkg\fR to install the
+add\-on. Run \fBmaelstrom_addon_package.pl \-\-help\fR for more information.
+.SS Manual Installation
+Look within the zip file for files named
+\fI%Maelstrom_Sprites\fR and/or \fI%Maelstrom_Sounds\fR or similar
+(the % may be missing, the _ may be a space, and/or the filenames
+may end with .bin). Copy these files to
+.P
+.nh
+\fB/usr/share/games/Maelstrom/%Maelstrom_Sprites\fR
+.br
+and/or
+.br
+\fB/usr/share/games/Maelstrom/%Maelstrom_Sounds\fR
+.hy
+.P
+\fBNOTE\fR: \fIThe % is important!\fR
+.SS Add\-On Limitations
+There is no way to install more than one add\-on at a time, or to disable
+the installed add\-on without uninstalling it. There is also no way to
+install add\-ons in a user's home directory, or any other place than
+the system\-wide game data directory.
+.SH FILES
+.TP
+\fB/usr/share/games/Maelstrom/\fR
+game data (images, music, sound)
+.TP
+\fB$HOME/.Maelstrom\-data\fR
+per\-user settings and high\-score records

+Maelstrom is a game similar to Asteroids.
+
+You pilot your ship through the dreaded "Maelstrom" asteroid belt --
+suddenly your best friend thrusts towards you and fires, directly at your
+cockpit. You raise your shields just in time, and the battle is joined.
+The deadliest stretch of space known to mankind has just gotten

+
+This package also comes with a script to create Slackware packages
+from the Maelstrom add-on graphics/sound files.
+Run 'maelstrom_addon_package.pl --help' for more information.
+
+Note to users of 64-bit and other non-x86 Slackware derivatives: you
+won't be able to host or join multiplayer games that use a server.
+Peer to peer (without the -server argument) multiplayer works OK though.

+
+Creates a Slackware tgz package from a Maelstrom addon zip file. The
+zipfile may be either a local file (e.g. "my_addon.zip") or a URL
+(e.g. "http://example.com/foo_addon.zip").
