games/doomlegacy: import doomlegacy-1.47.2

This is one of the most popular Doom source ports.
It enhances Doom with things like:
- Free Look
- OpenGL renderer
- Heretic support,
- TCP/IP networking
and much more.

Doom Legacy can play Doom, Boom, Marine's Best Friend (MBF), and Heretic maps.
In addition to the original games by id Software and Raven Software, there are
hundreds of free, fan-made maps available on the Internet. These maps are
typically distributed as PWAD files, which are not fully self-contained.
For each game you will also need the corresponding IWAD data file, which
contains all the graphics, wall and floor textures, sounds, and music for that
game. For example, if you want to play Doom II maps, you'll need the IWAD file
doom2.wad, or one of the free replacements.

Legacy has implemented the fundamental and de-facto-standard Boom extensions,
and the Marine's Best Friend (MBF) extensions. Legacy also has implemented
among other things 3D floors, swimmable water and other special effects using
extended linedef codes, and supports the FraggleScript scripting language.

This package contains the SDL build of Doom Legacy.

+.SH DESCRIPTION
+
+The following information is quoted from Reference Manual:
+.PP
+.B http://doomlegacy.sourceforge.net/docs/legacy.html
+.PP
+
+Doom Legacy can play Doom, Boom, Marine's Best Friend (MBF), and Heretic maps.
+In addition to the original games by id Software and Raven Software, there are
+hundreds of free, fan-made maps available on the Internet. These maps are
+typically distributed as PWAD files, which are not fully self-contained.
+For each game you will also need the corresponding IWAD data file, which
+contains all the graphics, wall and floor textures, sounds, and music for that
+game. For example, if you want to play Doom II maps, you'll need the IWAD file
+doom2.wad, or one of the free replacements.
+
+Legacy has implemented the fundamental and de-facto-standard Boom extensions,
+and the Marine's Best Friend (MBF) extensions. Legacy also has implemented
+among other things 3D floors, swimmable water and other special effects using
+extended linedef codes, and supports the FraggleScript scripting language.
+
+Legacy includes two different graphics engines, the old Doom software renderer
+(with many improvements) and an OpenGL-based hardware renderer.
+The OpenGL renderer is shinier and has fancier effects than the software one,
+but it does not do everything that the software renderer does. It does have
+coronas, explosion light, and other light effects that the software renderer
+does not do.
+Some wads rely upon violating wad rules to get trick effects. Most rely upon
+tricking the software renderer into not drawing something. Using those wads
+with the OpenGL renderer you will see holes in the floor and ceiling, and
+warning messges about polygons.
+
+The first game console we know of was from id Software's game Quake.
+We have been inspired by it and have tried to implement the same functionality
+for the benefit of Quake/Doom fans.
+
+Since Legacy 1.2, the network part of Doom has been totally rewritten.
+It now uses a better transfer method for the packets, (which is usually faster),
+and also implements a basic Client/Server model, where some critical game
+options are changeable only by the server in multiplayer games. Since the
+network communication is faster, we have upped the maximum number of players to
+32!

+Set PWAD (Patch WAD) files to use.

+Forces a particular game mode to be used.
+.br
+Examples for mode: doom, doomu, doom2, heretic
+.br
+(See Reference Manual for complete table)

+.BI -home " directory
+Home directory location, where your configfiles and savegames are kept.

+.BI -iwad " file
+Set the main IWAD (Internal WAD) file to use.
+This also determines the game mode when -game is not used.
+.TP
+.BI -noendtext
+Suppress the game EndText screen, which could disrupt some terminal emulations
+because of the special character attributes used.
+.TP
+.BI -opengl
+Hardware accelerated rendering using the OpenGL library.
+Will use hardware acceleration for OpenGL if available.
+If the video card does not have OpenGL hardware acceleration then it will use
+the OpenGL emulation in software, which is very slow.

+.BI -warp " num
+Select the map, start game immediately.
+.br
+In DoomII, -warp 13 will goto MAP13.
