+clonekeen (open source engine for id Software's Commander Keen game)
+
+CloneKeen is an open-source clone of ID's classic DOS game Commander
+Keen. CloneKeen runs under many platforms including Linux & win32. There
+are some improvements over the original such as 2-player support. Original
+game data files are required.
+
+clonekeen is able to run Commander Keen episodes 1, 2, and 3. Episodes
+4 through 6 are not yet supported. Copy the *.ck1, *.ck2, and/or *.ck3
+files from the game installation directory to /usr/share/games/clonekeen
+
+Optionally, the package can include the shareware (episode 1) game data
+files. To do this, download 1keen.zip:
+
+ftp://ftp.3drealms.com/share/1keen.zip
+
+...and place it in the directory where the SlackBuild script is. Also
+you must install libdynamite (available from SBo), since it's required
+to extract the game data. After running the SlackBuild script, the
+resulting package can be installed on a system without libdynamite
+(it's only required at build time). The extractor may also be useful
+for extracting the .SHR files from uninstalled copies of the commercial
+Commander Keen games (not tested by author).

+.TH CLONEKEEN 6 "March 25, 2010"
+.SH NAME
+clonekeen \- Clone of id Software's "Commander Keen" game
+.br
+.SH SYNOPSIS
+.B clonekeen
+[\fIwarplevel\fR]
+[\fIOPTIONS\fR]
+.SH DESCRIPTION
+CloneKeen is an almost almost complete open\-source clone of
+the old classic DOS game, \fICommander Keen: Invasion of the
+Vorticons\fR by ID Software. CloneKeen requires the original game
+data files to work. You can play all three episodes of the game
+(but not the later episodes 4 through 6, nor "Keen Dreams").
+.PP
+CloneKeen tries to mostly replicate the original game,
+however there are also a number of improvements,
+including smoother scrolling, better graphic effects
+in some parts of the game, and 2\-player support.
+.PP
+See story.txt for a description of the game's plot.
+.SH OPTIONS
+.TP
+\fBwarplevel\fR

+be enabled with -cheat or through the options menu. C+T+SPACE and G+O+D will
+always work.
+.TP
+\fBG+O+D\fR
+God \- Toggles GOD mode. You can't protect yourself
+ from dying if you fall off the map though.
+ (Use TAB to revive in this case).
+.TP
+\fBTab\fR
+Noclip/Revive \-
+Turns off clipping, allowing you to walk through
+ walls / Aborts a dying sequence.
+.TP
+\fBC+T+Space\fR
+All Items \- Gives all items, similar to the original.
+.TP
+\fBF2\fR
+Nofall \- Disables gravity, so Keen can walk on air.

+.SH GAMEPLAY
+(taken/modified from the original game's in\-game help)
+.PP
+When you are on the Mars map, you may be blocked by a city, shrine, or other
+obstacle.  You must enter the city (press Ctrl) and finish it
+before proceeding.
+.PP
+When you enter a city, you can get things by simply running into them.
+.PP
+If you cannot pass through a door, there may be a "keycard" that the door
+requires.  This keycard will be the same color as the door.
+.SH TREASURES
+(taken/modified from the original game's in\-game help)
+.PP
+\fBLollipop\fR \- 100 points
+.br
+\fBSoda\fR \- 200 points
+.br
+\fBPizza\fR \- 500 points
+.br
+\fBBook\fR \- 1000 points
+.br
+\fBTeddy Bear\fR \- 5000 points
+.PP
+You get an extra Keen every 20,000 points.
+.SH FILES
+.TP
+\fB~/.clonekeen\fR
+Per\-user savegames and config data. This directory is created the first
+time you run \fBclonekeen\fR.
+.TP
+\fB~/.clonekeen/defaultargs\fR
+Default arguments to pass to the game. Good candidates are \-fs, \-dbl,
+and/or -cheat. Put the arguments in the file on the same line,
+separated by spaces, e.g.:
+.PP
+\fBecho "-dbl -fs -cheat" > ~/.clonekeen/defaultargs\fR
+.TP
+\fB/usr/share/games/clonekeen/\fR
+System\-wide game data files (including the ones that come with
+the original game). Data files may be named in all\-uppercase or
+all\-lowercase (EGAHEAD.CK1 or egahead.ck1, or even mixed case like
+EGAHEAD.ck1 or egahead.CK1, but not egaHead.ck1)
+.TP
+\fB/usr/games/clonekeen\-bin\fR
+Main game binary. Generally not to be run directly: it expects to find the
+data files in the current dir, and writes config/savegame data in the
+current dir. Use the \fBclonekeen\fR wrapper script instead.
+.TP
+\fB/usr/games/clonekeen\fR
+Wrapper script.  Creates ~/.clonekeen, populates it with symlinks to the
+game data files, runs the main binary.
+.SH BUGS
+Actually not bugs, these are features that were in the original DOS version
+of the game that are not (yet?) implemented in clonekeen:
+.PP
+No way to customize keyboard controls
+.PP
+No support for joystick controls
+.PP
+No support for in\-game help (probably just as well, the help talks about
+joysticks, and customizing keyboard controls...)
+.PP
+Also, the DOS build of clonekeen appears to support up to 4 (or maybe
+only 3) player
+games, but the Linux build only defines enough control keys
+for 2 players.
+.SH AUTHOR
+clonekeen was written by Caitlin Shaw.
+.PP
+This manual page and the wrapper script were written by B. Watson for the SlackBuilds.org project.

+- Stops segfaulting on exit due to double-free bug

+- Sets the default frameskip to 1. This is because there is no

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.

+            COMMANDER KEEN
+                 in
+     "Invasion of the Vorticons"
+
+
+Billy Blaze, eight year-old genius, working diligently in his backyard
+clubhouse has created an interstellar starship from old soup cans, rubber
+cement and plastic tubing.  While his folks are out on the town and the
+babysitter has fallen asleep, Billy travels into his backyard workshop, dons
+his brother's football helmet, and transforms into...
+
+  COMMANDER KEEN--defender of Earth!
+
+In his ship, the Bean-with-Bacon Megarocket, Keen dispenses galactic justice
+with an iron hand!
+
+
+   Episode One: Marooned on Mars
+
+
+In this episode, aliens from the planet Vorticon VI find out about the eight
+year-old genius and plan his destruction.  While Keen is out exploring the
+mountains of Mars, the Vorticons steal vital parts of his ship and take
+them to distant Martian cities!  Can Keen recover all the pieces of his
+ship and repel the Vorticon invasion?  Will he make it back before his
+parents get home?  Stay tuned!
+
+   WHAT THE VORTICONS HAVE STOLEN
+
+The Bean-with-Bacon Megarocket was constructed from objects around the house
+that you have "modified" into starship parts:
+
+	 JOYSTICK (from your brother's video game) Manual flight control.
+
+	 CAR BATTERY (from your Mom's car) Electrical systems power.
+
+	 VACUUM CLEANER (from the kitchen, heavily modified) Ion propulsion
+unit (with carpet height adjustment).
+
+	 EVERCLEAR (from your Dad's liquor cabinet) Fuel.
+
+
+
+The Vorticons have taken these pieces to the far reaches of Mars and are
+guarding them.  You must find the members of this Vorticon outpost and wrest
+the parts back from their wicked, clawed hands!
+
+         INFORMATION ON MARS
+
+Unbeknownst to NASA, when the Viking Lander settled to the surface of
+Mars, it caused a major political upheaval.  Viking actually landed on the
+despotic Martian king!  The Yorps (the extremely friendly one-eyed
+Martians) were free from enslavement, and the Gargs (the vicious, aggressive
+Martians) were angry.
+
+The Martians created robots for menial work and guard duties.  Beware of the
+tank-like Guard Robots--they are VERY good at what they do.
+
+Martians have been visiting Earth in UFOs for decades.  Why?  They come to
+Earth for one reason--THEY WANT OUR TOYS.  Hula hoops and skateboards are
+holy objects to them!  Who knows...you may find some toys useful!
+
+There are signs everywhere.  You haven't been able to decipher them yet....
+
+        THE ADVENTURE BEGINS...
+
+Your task is before you.  Go get 'em, Commander Keen!
+
+______________________________________
+
+
+And don't miss episodes Two and Three in the "Invasion of the Vorticons"
+trilogy!
+
+
+  Episode Two: The Earth Explodes
+
+Keen has assembled his ship and returned home, only to find the Vorticon
+Mothership hovering over the Earth, ready to destroy all of Earth's cities
+and wonders!  Keen must sneak aboard, stop the imminent destruction of Earth
+and find a way to neutralize the Mothership!  If he fails...THE EARTH
+EXPLODES! (No pressure.)
+
+   Episode Three: Keen Must Die!
+
+Keen flies to the planet Vorticon VI to once and for all rid the galaxy of
+the Vorticon menace.  The entire planet is waiting for his arrival, with
+only one order given--Commander Keen must die!  What evil being is behind
+all this?  Stay tuned for the climactic, shocking finale!
+
+
+Commander Keen says: "You won't believe what happens in Episode Three!"
