-# SRB2Kart: Saturn
+# SRB2Kart-Saturn
+
+SRB2Kart-Saturn is a modification of SRB2Kart with a focus on new Features, Fixes, Optimizations and general Improvements, all while retaining 100% compatibility with vanilla SRB2Kart.

 [SRB2Kart](https://srb2.org/mods/) is a kart racing mod based on the 3D Sonic the Hedgehog fangame [Sonic Robo Blast 2](https://srb2.org/), based on a modified version of [Doom Legacy](http://doomlegacy.sourceforge.net/).

-## Saturn Features (Take a look at the "Saturn Options" menu c;)
+For more information on Saturn´s features check out the changelogs on the [Releases](https://github.com/Indev450/SRB2Kart-Saturn/releases) page and the ingame "Saturn Options" menu.

- Sprites player rotation on slopes; going on hills, levitate, going down, and so on alters your sprites (configurable)
- You can alter all the base kart HUD element offsets on the fly in the Saturn Options settings menu
- `addfilelocal` Command, for those who want to use things like their custom hud in netgames (Same as addfile but completely client sided)
- Palette rendering, make the OpenGL renderer (almost) look like software mode!
- OpenMPT for Tracker module playback instead of GME
-  - Fixes looping and sounds better
-  - Allows filter configuration
- Colourize your Kart HUD, to either your player color or whichever colour you like! (optional / requieres extra2.kart file)
- The minimal brightness with Shaders can be configured, now you can seeeee in dark areas (0-255 , uses Sector brightness values)
- Lua HUD hooks for Intermission (ex: You can make hostmod votes still visible during intermission!)
- Lua HUD hooks for Vote Screen (ex: You can make hostmod votes still visible during map vote screen!)
- Saltyhop! do a funny hop
- Smaller Speedometer (optional / requieres extra.kart file)
- Record Attack input display can now be used everywhere
- Smaller minimap icons and also show player names on the minimap (toggable)
- Support for animated votescreens!
- `showmusiccredit` command, shows you the current music track again
- `listskins` show a list of all skins currently loaded
- Visual Portals from Haya's HEP Client
- Horizonline effect in OpenGL (watch the endless bricks on SNES Bowsers Castle!)
- Localskins! use whatever skin you like!
- Toggable lowercase menu's also from Haya's HEP client
- Everything that Galaxy has
+Also be sure to check the LUASTUFF file for more information on all the extra lua features Saturn has.

-## Improvements / Bug fixes
-
- Replay size has been increased to 10MiB minimum, to make replay overflows very unlikely to happen
-  - can be set to 100MiB max with `maxdemosize` command in console
- Music changes now properly show the music credits (ex: Kart maps with easter eggs that alter the music)
- - The mapper still has to provide a MusicDEF for this to work.
- Configurable chatlog length (yay can read those messages from 30 mins ago without opening log.txt)
- Configurable timeout for waiting to join a full server (in vanilla this is capped to 5 minutes before it boots you out)
- Characters now spin in skin selection menu (configurable)
- HTTP Addon download speed has been raised dramatically
-  - configurable with `downloadspeed` command
- HWR Drawnodes have been refactored, this should fix a few rare crashes esp in regards to OpenGL Visportals
- The Position Number in the corner is alot smaller now (half the size!)
- Toggable Lap animation
- Main menu shows the current renderer being used
- MSAA and A2C Antialiasing support (Configurable in renderer.txt file)
- A simple button to rejoin your last visited server
- Ability to show ALL maps in the mapselect screen, this includes hidden or hellmaps "showallmaps yes/no"
- Ability to toggle the Stagetitlecard "maptitles on/off"
-
-## Performance / Debugging
-
- Access for `mobj_t` and `player_t` fields from Lua has been completely rewritten, for much better performance with many Lua scripts
- Lua shows Tracebacks whenever an error occurs
- The Lua Perfstats page now has multiple pages and is more organized (ps_thinkframe_page X in console)
- People with lower end hardware can disable "screen textures" with "gr_screentextures" command, huge performance gain with minimal visual loss
-  - Intermission backgrounds, heat wave effects and etc are broken with this
- `ffloorclip`, exclusive to Software, which boosts performance on maps with many Floor over Floor sectors
-
-## Technical fixes
-
- ZFigthing Textures in Opengl mode have been fixed in engine (well almost all of it)
- FOFs intersecting with slopes have less issues and now render correctly in Opengl
- Midtextures on slopes in Opengl are fixed, many weird guardrails and fences, aswell as some of those sticking out textures from the ground on some maps should be gone
- The annoying depraction messages for `P_TeleportMove` and `P_AproxDistance` have been silenced
- Silenced the annoying "cant find next map..." messages as theyre super useless and annoying anyways
- Added a small cooldown on `map` command due to spamming causing a SIGSEGV
- Many bugfixes to the Software renderer, so its much less prone to crashing
- Many bugfixes to the OpenGL renderer (too many too list all of them here; check the changelogs for more information)
- Bugfixes to the soundsystem, mainly regarding Sound muting
- Refactored Zone Memory Allocations (helps a bit with large maps)
- Many many more crash fixes and other bugfixes to the basegame (too many too list all of them here; check the changelogs for more information)
-
- Crash Backtraces have been replaced by libbacktrace (except for 32bit Windows builds)
-Crashlogs now contain alot more informations. and even more if your build has debug symbols
-Also allows 64bit Windows builds to produce Crashlogs!
-
-## MISC
- Bird's Camera Tilting feature is no longer turned on by default
- Bird's warning on the title screen has been removed
-
-## Bugs
- On maps which change the song multiple times on map start (exp: Wandering Falls) may show multiple music credits appearing
- A2C antialiasing makes transparent surfaces even more transparent
- You tell us! c:
-
-## Note
-Check the LUASTUFF file for more information on all the lua things Saturn has.
+We also have a Flatpak available on [Flathub](https://flathub.org/en/apps/org.srb2.SRB2Kart-Saturn)! (many thanks to riomccloud!)

 ## Dependencies

 - SDL2-Mixer (Linux/OS X only)
- libupnp (Linux/OS X only)
 - libgme (Linux/OS X only)
 - libopenmpt (Linux/OS X only)

 ## Compiling

 See [SRB2 Wiki/Source code compiling](http://wiki.srb2.org/wiki/Source_code_compiling). The compiling process for SRB2Kart is largely identical to SRB2.

+For Windows only the Makefile build system with GCC or Clang compiler is supported.
+Visual C++ (MSVC) is unsupported.
+
+64-bit Windows builds are supported and recommended over 32-bit builds, they will build automatically when using the MSYS2 MinGW 64-bit executable (requires the mingw-w64-x86_64-gcc package), no extra flags needed!
+The specific DLLs can be found under /libs/dll-binaries/(i686 for 32bit/x86_64 for 64-bit)/ or in the Release packages
+
+MacOS and Linux can be build with CMake, but it is recommended to use the Makefile for Linux over CMake
+
+Alternatively the [srb2bld](https://github.com/Bijman/srb2bld) script by Bijman can be used aswell!

-SRB2 Debian package!
-Hi there, to rebuild these packages just use debuild in the root source directory (not /src!).
-You can build these with or without a key if you want, but if you want to put these on a repo,
-generate your own GnuPG key as per the https://help.ubuntu.com/community/GnuPrivacyGuardHowto
-instructions and pass the -k<keyid> command to debuild. Make sure you export the key footprint
-and give them to your users to install with apt-key add. Thanks!
-
- -- Callum Dickinson <gcfreak_ag20@hotmail.com>  Fri, 26 Nov 2010 18:25:31 +1300

---------------
-
-
-Templating
-
-Note that you MUST run [repo-root]/debian_template.sh before running debuild
-on these scripts! debian_template.sh fills these template files with working values.
-
-You should also set PACKAGE_NAME_EMAIL="John Doe <jdoe@example.com>" to match
-the identity of the key you will use to sign the package.
-
-
-Building for Launchpad PPA
-
-Use these steps to prepare building a source package for Launchpad:
-
-    1. cd [repo-root]
-    2. git reset --hard; git clean -fd; git clean -fx;
-       * Resets your repo folder to a committed state and removes untracked files
-       * If you built srb2-data in the assets/ folder, MAKE SURE THAT FOLDER DOES NOT HAVE ASSETS,
-         OR THEY MAY BE INCLUDED IN THE MAIN SOURCE PACKAGE!
-
-Build the source package:
-
-    1. source [repo-root]/debian_template.sh
-       * Initializes defaults for the package variables and fills in templates.
-    2. debuild -S (builds the source package for Launchpad)
-
-
-Signing for Launchpad PPA
-
-First, follow Callum's instructions to generate a GnuPG key with your identity. You will need
-to publish the fingerprint of that key to Ubuntu's key server.
-
-    https://help.ubuntu.com/community/GnuPrivacyGuardHowto#Uploading_the_key_to_Ubuntu_keyserver
-
-Next, you will have to add that key fingerprint to your Launchpad account. Go to your Launchpad
-profile and click the yellow Edit button next to "OpenPGP keys". Once you add the key, you can
-upload signed source packages and publish them onto your PPA.
-
-IF YOU UPLOAD A PACKAGE and Launchpad does NOT send you a confirmation or rejection email, that
-means your key is not set up correctly with your Launchpad account.
-
-Finally, if your packages have not already been signed, follow these steps:
-
-    1. cd ..
-       * Packages are located in the parent folder of where debuild was called
-    2. debsign "srb2_[version]_source.changes"
-       * You may need to specify -k [key-fingerprint]
-
-
-Uploading for Launchpad PPA
-
-Follow the instructions at <https://help.launchpad.net/Packaging/PPA/Uploading> to upload
-to your PPA and have Launchpad build your binary deb packages.

-Description: A cross-platform 3D Sonic fangame
- Sonic Robo Blast 2 is a 3D open-source Sonic the Hedgehog
- fangame built using a modified version of the Doom Legacy
- port of Doom. SRB2 is closely inspired by the original
- Sonic games from the Sega Genesis, and attempts to recreate
- the design in 3D. It features tons of levels, enemies, speed,
- and quite a lot of the fun that the original Sonic games provided.

-   ================================================================
-   How to add Low-res modes to your XF86Config under Linux MANUALLY
-   ================================================================
-
-   I TAKE NO RESPONSIBILITY FOR ANY DAMAGE DONE TO YOUR EQUIPMENT!!!
-
-   This document explains how to add low-res modes like 320x200 to your
-   X-Server configuration, because some new setup tools for the X-Server
-   do not support this. ONLY RECOMMENDED FOR USERS WHO KNOW WHAT THEY DO!
-
-   I do not take any responsibility for damage done to your monitor, your
-   videocard, your harddisk, your cat, your dog or anything else!!!
-   IMPORTANT IS, THAT YOUR "HorizSync" AND "VertRefresh" VALUES REALLY
-   MATCH YOUR MONITOR! OTHERWISE YOUR MONITOR CAN BLOW UP!!!
-
-   OK, if you have read up to here, you either know what you do or really
-   die-hard want those low-res modes. Here is what to do:
-   Look up your XF86Config. Is is either in /etc or in /etc/X11. Here is
-   what you have to add to the definition of your modeslines:
-
-# Low-res Doublescan modes
-# If your chipset does not support doublescan, you get a 'squashed'
-# resolution like 320x400.
-
-# 320x200 @ 70 Hz, 31.5 kHz hsync, 8:5 aspect ratio
-Modeline "320x200"     12.588 320  336  384  400   200  204  205  225 Doublescan
-# 320x240 @ 60 Hz, 31.5 kHz hsync, 4:3 aspect ratio
-Modeline "320x240"     12.588 320  336  384  400   240  245  246  262 Doublescan
-# 320x240 @ 72 Hz, 36.5 kHz hsync
-Modeline "320x240"     15.750 320  336  384  400   240  244  246  262 Doublescan
-# 400x300 @ 56 Hz, 35.2 kHz hsync, 4:3 aspect ratio
-ModeLine "400x300"     18     400  416  448  512   300  301  302  312 Doublescan
-# 400x300 @ 60 Hz, 37.8 kHz hsync
-Modeline "400x300"     20     400  416  480  528   300  301  303  314 Doublescan
-# 400x300 @ 72 Hz, 48.0 kHz hsync
-Modeline "400x300"     25     400  424  488  520   300  319  322  333 Doublescan
-
-   If your video card only supports a specific set of discrete dotclocks
-   (RAMDAC) you may have to replace the dotclocks given here by one of the
-   specified (e.g in the first modeline the dotclock is 12.588 MHz). I believe
-   that nowadays all cards and monitors should work with these settings, but
-   if you have outdated hardware you better check the frequencies yourself. If
-   there is any uncertainty, please check the "XFree86 Video Timings HOWTO".
-
-
-   Then have a look at the section "Screen" with the appropriate driver
-   (usually either "svga" or "accel"). Under Subsection "Display" there
-   are modes for the given color depth. Add the desired modes. As an
-   example I give you my screens definition here with low-res modes in
-   16 bit color depth:
-
-Section "Screen"
-    Driver      "accel"
-    Device      "3D Charger"
-    Monitor     "Iiyama Pro 450"
-    DefaultColorDepth 16
-
-    Subsection "Display"
-        Depth       8
-        Modes       "1280x1024" "1024x768" "800x600" "640x480"
-        ViewPort    0 0
-        Virtual     1280 1024
-    EndSubsection
-    Subsection "Display"
-        Depth       16
-        Modes       "1152x864" "1024x768" "800x600" "640x480" "400x300" "320x200" <- THIS IS ACTUALLY WHAT YOU WANT!!!
-        ViewPort    0 0                                       ^^^^^^^^^^^^^^^^^^^
-        Virtual     1152 864
-    EndSubsection
-    Subsection "Display"
-        Depth       24
-        Modes       "800x600" "640x480"
-        ViewPort    0 0
-        Virtual     800 600
-    EndSubsection
-    Subsection "Display"
-        Depth       32
-        Modes       "800x600" "640x480"
-        ViewPort    0 0
-        Virtual     800 600
-    EndSubsection
-EndSection
-
-   Once again: important is, that you edit the correct Screen section.
-   If you use the SVGA Server and edit the ACCEL Server, you might
-   wonder where your new modes have gone.
-
-   If everything went fine and you want to say thank you, just write
-   to "metzgermeister@users.sourceforge.net". If your monitor blew
-   up and you want to kill me, find me playing Legacy or Q3A on the net
-   and frag me (with your second monitor, hehe).

- here.
-
- If you find a solution to a problem that was not listed here,
- please tell us so that we can update the FAQ and help other people!

- * under win95 or OS/2, I don't have enough memory. How can i handle with ?
-
-   Tell win95 to put more dpmi memory for your dos box.
-   Or use the -mb option.
-
-
-
- ---------------------------
- [1] MOUSE/JOYSTICK/KEYBOARD
- ---------------------------
-
- * My mouse/joystick does not work in SRB2.
-
-   First, check that the mouse/joystick is activated : go at the
-   console and type either 'use_mouse' (or use the respective
-   menuitem) or 'use_joystick'.
-
-   If it tells '0' or off than the mouse/joystick is not used,
-   set the variable to 1. eg: 'use_mouse 1'.
-
-   For the joystick, different values will support different
-   types of joystick, check the console documentation for the
-   command 'use_joystick' for more.
-
-   Even if the mouse or joystick is activated, you have to
-   set up the contols into the Setup Controls menu. That is:
-   tell what use you will make of the mouse/joystick buttons.
-

- [2] VIDEO
- ---------
-
-
- * Where are the other video modes ? I have only '320x200' in the
-   Video Modes menu.
-
-   DOS
-   ---
-
-   SRB2 adds new video modes only if a VESA2 (or better) driver
-   is present. The VESA2 driver is a standard of 'talking' between a
-   program and the huge amount of different graphics cards
-   available today.
-
-   If you don't have a VESA2 driver, you can download UNIVBE, or
-   SMART DISPLAY DOCTOR from
-
-   http://www.scitechsoft.com/products/ent/free_titles.html
-
-   or if you have an S3 based card, you can download the free
-   software called 'S3VBE'.

-
- * The game doesn't restore the video mode I have chosen the last time
-   I played SRB2.
-
-   The current video mode has to be made the 'default' so that it is
-   saved to the config : press the key 'D' on the Video Options menu
-   to set the current video mode the default.
-
-  * I have some problems with OpenGL mode
-
-   Have a look at the FAQ for OpenGL on the glLegacy web site:

-   http://www.doomnation.com/gllegacy/faqe.htm
-
- # Linux: I only have a 1024x768 (or 800x600, 1280x1024, ...) resolution
-   in fullscreen mode under X and SRB2 is really really slow. Can I
-   have lower resolutions like 320x200 in fullscreen mode as well?

-   Probably yes. SRB2 can only use the resolutions offered by the
-   X-Server. So if all fullscreen modes have a very high resolution you
-   have to modify /etc/XF86Config (or /etc/X11/XF86Config). Use XF86Setup
-   (or the appropriate tool coming with your distribution - sax,
-   xf86config, ...) to do this.
-   If you do not succeed there, you can enter them manually into your
-   XF86Config file. ONLY RECOMMENDED FOR USERS WHO KNOW WHAT THEY DO!
-   For a short guide on how to do this, have a look at the file
-   "Doublescan.txt".
-   In case of doubt consult the XFree86-HOWTO (or ask your system
-   administrator :).
-
- # Linux: I cannot have any fullscreen modes at all!
-
-   You have only modes above 1024x768 in your XF86Config. Proceed as
-   described above.
-
- # Linux: After a certain idle time my screensaver jams the display of
-   SRB2. I can still operate SRB2, but I do not see what's happening
-   and the screensaver won't go away.
-
-   You probably have KDE. The KDE screensaver does not obey the screensaver
-   rules (at least mine, version 1.1). The solution is to deactivate the
-   KDE screensaver and use another screensaver (like the xscreensaver,
-   e.g.). But the hell, when you started SRB2 you should have played it
-   as well and not left it alone!!!

- [3] SOUND
- ---------
-
- + DOS:I can't have CD audio music, why ?
-
-   Make sure that the MSCDEX driver version 2.0 or later is loaded.
-   If it says 'MSCDEX version xxx' at game startup, and you still
-   don't hear the cd music, then probably your card doesn't respond
-   when SRB2 tries to set the cd volume. If so, make sure your sound
-   card's mixer have the cd volume set up so that you can hear something.
-
- + When the CD plays, the game is very 'jerky'. It doesn't do that when
-   I type 'cd off' in the console.
-
-   You have an old/bad cd driver, that can take up to a second to
-   respond to cd driver commands. Either get the latest version of
-   your driver, or turn cd update off. Check 'cd_udpate' in the
-   console documentation for more.
-
- * DOS:How can I *ALWAYS* disable the sounds or music of the game ?
-
-   Edit the allegro.cfg file and set digicard/midicard to 0 (none)
-
- * DOS:My sterero sound is reversed, how can I set it the right way ?
-
-   Change the console variable 'stereoreverse' to either 1 or 0.
-   Or, you can edit the allegro.cfg file, and set the 'flip_pan' variable.
-
-
- * DOS:The sounds are too 'slow', or 'low-pitched'
-
-   It seems to be a problem of the auto-detection of some 8bit sound
-   cards. You will have to set manually the 'sb_freq' value in the
-   allegro.cfg file to a lower value : 11906, 16129.
-
- * DOS:SRB2 doesn't play any sound/music, but I have a sound
-   blaster genuine/compatible card.
-
-   If you have a genuine or compatible SoundBlaster card, it is very
-   important that you set the BLASTER environment variable.
-
-   If you are playing under DOS, and never installed your sound card
-   under DOS, run the setup of your sound card for DOS.
-
-   Check if the BLASTER variable was set: type 'SET' under dos
-   (or DOSbox)
-
-   Do you see something like 'BLASTER=A220 I5 D1 ...' ?
-
-   Yes? If you don't hear sounds/music, then tweak the settings in the
-   allegro.cfg file until you get something, first try changing the
-   type of the sound card, it is not always properly detected.
-
-   No? You have to set this variable in order that your sound card is
-   detected. Run the setup that was shipped with your sound card, and
-   make sure you run the setup for DOS too, it will usually add a
-   line of the type 'SET BLASTER=... ...' in the autoexec.bat file.
-
-
- * DOS:How can I have better midi music on my 8bit sound card ?
-
-   Use the DIGMID driver, it is supported in SRB2.
-
-   What the hell is this? Well, the Gravis Ultrasound uses digital
-   samples to play midi music. On a simple 8bit card, you can use digital
-   samples too, which will sound usually better than what is output
-   by the poor fm synthesis chip of 8bit cards.
-
-   You will need to get a Gravis Ultrasound patch set, you can find
-   several ones for free on internet, it consists of a bunch of '.pat'
-   files which are the digital samples to play the midi instruments
-   (eg: piano, conga, guitar, ect.).
-
-   Check the Allegro homepage for some links to GUS patches:
-   http://alleg.sourceforge.net/digmid.html
-   http://alleg.sourceforge.net/
-   http://www.talula.demon.co.uk/allegro/digmid.html
-   http://www.talula.demon.co.uk/allegro/
-
-   Now to activate the DIGMID driver:
-
-   Set the 'midi_card' value to 8 (DIGMID) in the allegro.cfg file.
-   Make sure you leave the 'digi_voices' blank, or set it to a low
-   value, because the midi music will use digital voices.
-   At the end of the allegro.cfg file, set the 'patches' value
-   to the path, where you have installed a Gravis Ultrasound midi
-   patch set. eg: patches = d:\music\midipat\
-
- # Linux: CD music does not work or only works when run as root.
-
-   We do not encourage you to run SRB2 as root (you never know
-   what SRB2 can do to your system - it's a mighty piece of code :).
-   There is a common problem with ATAPI CD-rom drives, which are
-   treated as harddisks. Usually there is a link /dev/cdrom pointing to
-   device hd[b,c,d]. As harddisks are not supposed to be read directly
-   via this device (especially not by a common user), there are no read
-   permissions for "all". For CD-roms you can savely set read permissions
-   unless you are very paranoid. Assuming your CD-rom drive is /dev/hdc,
-   set permissions with "chmod +r /dev/hdc" (as root). SCSI CD-rom drives
-   should not have this problem. But if they do, proceed as described
-   with ATAPI drives.
-
- # Linux: The CD music volume is not set properly.
-
-   Go to the console and type "jigglecdvolume 1".
-
- -----------
- [4] NETWORK
- -----------
-
- * Where can I find Internet servers ?
-
-   For the moment there is one public server.
-   http://srb2.servegame.org/ Master server web page
-   srb2.servegame.org:28910 current Master Server
-
- * When I start SRB2 with -server or -connect it say :
-    "BinToPort: Address already in use (EADDRINUSE)"
-
-   It appears only when SRB2 crashes or when you leave with ctrl-break.
-   use -udpport 12345 (or any other free slot) on both sides (client and
-   server).
-
-   This can also happens when there is already a SRB2 running on your
-   computer if you whant to try two SRB2 running on the same computer
-   use -clientport 12345 (or any other free slot). Then the second will
-   connect to the first one.
-
- * Do you use the tcp protocol ?
-
-   No, we use the udp protocol which is faster, but don't worry udp is a
-   part of the internet protocol.
-
-
- -------------------
- [5] Troubleshooting
- -------------------
-
- # Linux: SRB2 is hung in fullscreen mode and won´t let me leave.
-   What shall I do?
-
-   Some people press the reset button, but hey, we are not in the
-   stoneage of operating systems! There are two "proper" ways to
-   get out: kill your X-Server. You can usually do this by pressing
-   "CTRL-ALT-BACKSPACE". But if you have other open applications with
-   important data (probably hacked away on your diploma thesis for 3
-   weeks without saving once) you can also kill SRB2 directly. Press
-   "CTRL-ALT-F2" and you will get to a console. Log in, type
-   "killall llxSRB2" and switch back to the X-Server with "CTRL-ALT-F7".
-   Some X-Server crash on this procedure - blame the X-Server for the
-   loss of 3 weeks work on your diploma thesis :)

-SVN-RULES
-
- As you can see, there is sub-directory in the repository, one for eatch
-  platform (djgpp (dos),win32,SDL) the root directory is for all platform,
-  so take care of the order we have put in.
- do not commit/upload tests of bugged code, try to fix a maximum of know
-  bugs and update know bugs list in source.txt. If you must commit your source
-  make your code in #ifdef so we can disable it
- SRB2 is a modification of doom/Doom Legacy source. We allow additionnal feature
-  and visual addition.
- Maximize communications between members, do not impose your changes, if your
-  are not sure about a feature/change, talk about it in irc://irc.esper.net/srb2 chat room.
-
-CODE-RULES
-
- We use no tab, 4 space indent, and tab size 8 (in case some tab have filtred
-  and for makefile)
- Self documented code, variable and function must have a name that help
-  understand the code, so do not call variable and function a,b, a2, ...
- the usage of extern in a c file is prohibited, except for declaration of a
-  function with body (so it is like public keyword in c++)
-  Also function protos haren't allowed for external function, put it un the
-  corresponding h file.
- Try to minimize #ifdef usage for :
-  - code readability
-  - the main code is for all port so if something is good for a platform all
-    platform can benefit by this feature
- Take care of platform dependent code, we would like to have code that work
-  on Dos, Win32, SDL, ... little and big endian, software/Glide/OpenGl.
-
-GOOD PRACTICE
-
- Try to put as mush static variable and function on module so it help to
-  understand the role of the varaible/function in the module also this
-  help the compiler to optimize
- minimise global variable
- make a log of your work, so you don't need to put a lot of comment in
-  the code, this will also help us to update the what's new section of doc
-  when doing final release

-2. Explanation of the code
-==========================
-
- 2.1 The memory model (original) (z_zone.c) (by BP)
- --------------------
-
- SRB2 allocate a heap of 6/32/48 megs at begining and provide a Z_Malloc function
- to allocate in this heap.
-
-   Z_Malloc( int size,int tag,void* user )
-
-    size is the size in byte
-    tag can be : PU_STATIC   allocated static (like malloc do)
-                             call Z_Free to free it
-                 PU_LEVEL    same as static but the zone is "tagged" with the
-                             tag PU_LEVEL, when calling
-                             Z_FreeTag (PU_LEVEL, PU_LEVEL) all zone tagged
-                             with PU_LEVEL are freed (at the end of the level)
-                 PU_CACHE    this one _can_ be freed automatiquely by one other
-                             call to Z_Malloc. the *user point to a pointer
-                             to this zone so when freed automatiquely the
-                             pointer is set to NULL so eatch time you use it
-                             you must check if the pointer is not NULL and
-                             reload it.
-
- (...)
-
- 2.2 Hardware Texture model (by BP)
- --------------------------
-
- Eatch texture/patch/flats/pic in SRB2 are converted to hardware texture at
- runtime (the GlideMipmap_s structure (hw_data.h)). I will call hardware
- texture a gr_texture so there is no confusion.
-
- To remind you :
-  - Texture are set of patch and are associate to linedefs (walls) can be
-    upper, lower or middle texture. It can have hole on it.
-  - patch are sprites (the doom patch are run of vertical lines)
-  - flats are used for floors and ceiling of sectors and have size of 64x64
-    it can't have hole on it
-  - pic are new legacy format for picture, it can only handle plain texture
-    like flats it is now used for hud in full screen for the main picture
-    of legacy and for coronas (the format was extended to handle 32 bit color
-    or intensity + alpha, not all are implemented at this time)
-
- Since patch, flat and pic are basic structure represented by only one lump in
- the wad, the wad loader allocate for eatch lump a GlideMipmap_s (cache3Dfx)
- and init data field to NULL. Since the data structure is allocated in
- PU_3DFXCACHE (like PU_CACHE) the data will be initilised when needed
- (hw_cache.c).
-
- The GlideMipmap_s structures for textures are initialized on
- HWR_PrepLevelCache (hw_cache.c) it is called in P_SetupLevel (load level)
- the number of textures is computed with TEXTURE1, TEXTURE2 lumps since this
- can be changed in runtime in SRB2 (load a wad while runing) it must be
- reallocated. Well, at this time it is realloceted at eatch level start. We
- can do better, since numtextures change only when a wad is loaded.
-
- The 3dfx driver use glide3, it load gr_texture in gr_texture memory of the
- card in fifo order when there is no more place it remove the first gr_texture,
- the downloaded field of GlideMipmap_s go to false and when needed it is
- reloaded in gr_texture memory. In OpenGl, since OpenGl keep texture in there
- own memory and handle gr_texture memory of the card we no more need to
- redownload it but if we not free time to time gr_texture memory in opengl,
- it will get alot of memory, so the gr_texture memory is cleared at eatch
- new level (same time of texture reallocation). Opengl and 3dfx link the
- loaded gr_texture with the nextmipmap field of GlideMipmap_s so before clear
- textures of the heap we MUST free gr_texture memory of OpenGl or 3dfx !
-
- SRB2 can also draw patch with a differant colormap (thanks to Hurdler).
- When needed it create the same gr_texture but just with a differant colormap.
- This one is linked with the original in the GlideMipmap_s with the
- nextcolormap field.
-
- So when a polygone with a gr_texture must be drawn, first we check if the
- gr_textures is not allready loaded in hadware memory (downloaded field) if
- not then we check if gr_texture data is there (not grabbed by z_malloc

 In general the functions provided by this library are async-signal-safe,

+Similar considerations apply when arranging to call libbacktrace
+from within malloc; `dl_iterate_phdr` can also call malloc,

+
+
+
+
+                Frequently Asked Questions about zlib
+
+
+If your question is not there, please check the zlib home page
+https://zlib.net/ which may have more recent information.
+The latest zlib FAQ is at https://zlib.net/zlib_faq.html
+
+
+ 1. Is zlib Y2K-compliant?
+
+    Yes. zlib doesn't handle dates.
+
+ 2. Where can I get a Windows DLL version?
+
+    The zlib sources can be compiled without change to produce a DLL.  See the
+    file win32/DLL_FAQ.txt in the zlib distribution.
+
+ 3. Where can I get a Visual Basic interface to zlib?
+
+    See
+        * https://marknelson.us/1997/01/01/zlib-engine/
+        * win32/DLL_FAQ.txt in the zlib distribution
+
+ 4. compress() returns Z_BUF_ERROR.
+
+    Make sure that before the call of compress(), the length of the compressed
+    buffer is equal to the available size of the compressed buffer and not
+    zero.  For Visual Basic, check that this parameter is passed by reference
+    ("as any"), not by value ("as long").
+
+ 5. deflate() or inflate() returns Z_BUF_ERROR.
+
+    Before making the call, make sure that avail_in and avail_out are not zero.
+    When setting the parameter flush equal to Z_FINISH, also make sure that
+    avail_out is big enough to allow processing all pending input.  Note that a
+    Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be
+    made with more input or output space.  A Z_BUF_ERROR may in fact be
+    unavoidable depending on how the functions are used, since it is not
+    possible to tell whether or not there is more output pending when
+    strm.avail_out returns with zero.  See https://zlib.net/zlib_how.html for a
+    heavily annotated example.
+
+ 6. Where's the zlib documentation (man pages, etc.)?
+
+    It's in zlib.h .  Examples of zlib usage are in the files test/example.c
+    and test/minigzip.c, with more in examples/ .
+
+ 7. Why don't you use GNU autoconf or libtool or ...?
+
+    Because we would like to keep zlib as a very small and simple package.
+    zlib is rather portable and doesn't need much configuration.
+
+ 8. I found a bug in zlib.
+
+    Most of the time, such problems are due to an incorrect usage of zlib.
+    Please try to reproduce the problem with a small program and send the
+    corresponding source to us at zlib@gzip.org .  Do not send multi-megabyte
+    data files without prior agreement.
+
+ 9. Why do I get "undefined reference to gzputc"?
+
+    If "make test" produces something like
+
+       example.o(.text+0x154): undefined reference to `gzputc'
+
+    check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
+    /usr/X11R6/lib. Remove any old versions, then do "make install".
+
+10. I need a Delphi interface to zlib.
+
+    See the contrib/delphi directory in the zlib distribution.
+
+11. Can zlib handle .zip archives?
+
+    Not by itself, no.  See the directory contrib/minizip in the zlib
+    distribution.
+
+12. Can zlib handle .Z files?
+
+    No, sorry.  You have to spawn an uncompress or gunzip subprocess, or adapt
+    the code of uncompress on your own.
+
+13. How can I make a Unix shared library?
+
+    By default a shared (and a static) library is built for Unix.  So:
+
+    make distclean
+    ./configure
+    make
+
+14. How do I install a shared zlib library on Unix?
+
+    After the above, then:
+
+    make install
+
+    However, many flavors of Unix come with a shared zlib already installed.
+    Before going to the trouble of compiling a shared version of zlib and
+    trying to install it, you may want to check if it's already there!  If you
+    can #include <zlib.h>, it's there.  The -lz option will probably link to
+    it.  You can check the version at the top of zlib.h or with the
+    ZLIB_VERSION symbol defined in zlib.h .
+
+15. I have a question about OttoPDF.
+
+    We are not the authors of OttoPDF. The real author is on the OttoPDF web
+    site: Joel Hainley, jhainley@myndkryme.com.
+
+16. Can zlib decode Flate data in an Adobe PDF file?
+
+    Yes. See https://www.pdflib.com/ . To modify PDF forms, see
+    https://sourceforge.net/projects/acroformtool/ .
+
+17. Why am I getting this "register_frame_info not found" error on Solaris?
+
+    After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
+    generates an error such as:
+
+        ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
+        symbol __register_frame_info: referenced symbol not found
+
+    The symbol __register_frame_info is not part of zlib, it is generated by
+    the C compiler (cc or gcc).  You must recompile applications using zlib
+    which have this problem.  This problem is specific to Solaris.  See
+    http://www.sunfreeware.com/ for Solaris versions of zlib and applications
+    using zlib.
+
+18. Why does gzip give an error on a file I make with compress/deflate?
+
+    The compress and deflate functions produce data in the zlib format, which
+    is different and incompatible with the gzip format.  The gz* functions in
+    zlib on the other hand use the gzip format.  Both the zlib and gzip formats
+    use the same compressed data format internally, but have different headers
+    and trailers around the compressed data.
+
+19. Ok, so why are there two different formats?
+
+    The gzip format was designed to retain the directory information about a
+    single file, such as the name and last modification date.  The zlib format
+    on the other hand was designed for in-memory and communication channel
+    applications, and has a much more compact header and trailer and uses a
+    faster integrity check than gzip.
+
+20. Well that's nice, but how do I make a gzip file in memory?
+
+    You can request that deflate write the gzip format instead of the zlib
+    format using deflateInit2().  You can also request that inflate decode the
+    gzip format using inflateInit2().  Read zlib.h for more details.
+
+21. Is zlib thread-safe?
+
+    Yes.  However any library routines that zlib uses and any application-
+    provided memory allocation routines must also be thread-safe.  zlib's gz*
+    functions use stdio library routines, and most of zlib's functions use the
+    library memory allocation routines by default.  zlib's *Init* functions
+    allow for the application to provide custom memory allocation routines.
+
+    Of course, you should only operate on any given zlib or gzip stream from a
+    single thread at a time.
+
+22. Can I use zlib in my commercial application?
+
+    Yes.  Please read the license in zlib.h.
+
+23. Is zlib under the GNU license?
+
+    No.  Please read the license in zlib.h.
+
+24. The license says that altered source versions must be "plainly marked". So
+    what exactly do I need to do to meet that requirement?
+
+    You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h.  In
+    particular, the final version number needs to be changed to "f", and an
+    identification string should be appended to ZLIB_VERSION.  Version numbers
+    x.x.x.f are reserved for modifications to zlib by others than the zlib
+    maintainers.  For example, if the version of the base zlib you are altering
+    is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
+    ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3".  You can also
+    update the version strings in deflate.c and inftrees.c.
+
+    For altered source distributions, you should also note the origin and
+    nature of the changes in zlib.h, as well as in ChangeLog and README, along
+    with the dates of the alterations.  The origin should include at least your
+    name (or your company's name), and an email address to contact for help or
+    issues with the library.
+
+    Note that distributing a compiled zlib library along with zlib.h and
+    zconf.h is also a source distribution, and so you should change
+    ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
+    in zlib.h as you would for a full source distribution.
+
+25. Will zlib work on a big-endian or little-endian architecture, and can I
+    exchange compressed data between them?
+
+    Yes and yes.
+
+26. Will zlib work on a 64-bit machine?
+
+    Yes.  It has been tested on 64-bit machines, and has no dependence on any
+    data types being limited to 32-bits in length.  If you have any
+    difficulties, please provide a complete problem report to zlib@gzip.org
+
+27. Will zlib decompress data from the PKWare Data Compression Library?
+
+    No.  The PKWare DCL uses a completely different compressed data format than
+    does PKZIP and zlib.  However, you can look in zlib's contrib/blast
+    directory for a possible solution to your problem.
+
+28. Can I access data randomly in a compressed stream?
+
+    No, not without some preparation.  If when compressing you periodically use
+    Z_FULL_FLUSH, carefully write all the pending data at those points, and
+    keep an index of those locations, then you can start decompression at those
+    points.  You have to be careful to not use Z_FULL_FLUSH too often, since it
+    can significantly degrade compression.  Alternatively, you can scan a
+    deflate stream once to generate an index, and then use that index for
+    random access.  See examples/zran.c .
+
+29. Does zlib work on MVS, OS/390, CICS, etc.?
+
+    It has in the past, but we have not heard of any recent evidence.  There
+    were working ports of zlib 1.1.4 to MVS, but those links no longer work.
+    If you know of recent, successful applications of zlib on these operating
+    systems, please let us know.  Thanks.
+
+30. Is there some simpler, easier to read version of inflate I can look at to
+    understand the deflate format?
+
+    First off, you should read RFC 1951.  Second, yes.  Look in zlib's
+    contrib/puff directory.
+
+31. Does zlib infringe on any patents?
+
+    As far as we know, no.  In fact, that was originally the whole point behind
+    zlib.  Look here for some more information:
+
+    https://www.gzip.org/#faq11
+
+32. Can zlib work with greater than 4 GB of data?
+
+    Yes.  inflate() and deflate() will process any amount of data correctly.
+    Each call of inflate() or deflate() is limited to input and output chunks
+    of the maximum value that can be stored in the compiler's "unsigned int"
+    type, but there is no limit to the number of chunks.  Note however that the
+    strm.total_in and strm_total_out counters may be limited to 4 GB.  These
+    counters are provided as a convenience and are not used internally by
+    inflate() or deflate().  The application can easily set up its own counters
+    updated after each call of inflate() or deflate() to count beyond 4 GB.
+    compress() and uncompress() may be limited to 4 GB, since they operate in a
+    single call.  gzseek() and gztell() may be limited to 4 GB depending on how
+    zlib is compiled.  See the zlibCompileFlags() function in zlib.h.
+
+    The word "may" appears several times above since there is a 4 GB limit only
+    if the compiler's "long" type is 32 bits.  If the compiler's "long" type is
+    64 bits, then the limit is 16 exabytes.
+
+33. Does zlib have any security vulnerabilities?
+
+    The only one that we are aware of is potentially in gzprintf().  If zlib is
+    compiled to use sprintf() or vsprintf(), then there is no protection
+    against a buffer overflow of an 8K string space (or other value as set by
+    gzbuffer()), other than the caller of gzprintf() assuring that the output
+    will not exceed 8K.  On the other hand, if zlib is compiled to use
+    snprintf() or vsnprintf(), which should normally be the case, then there is
+    no vulnerability.  The ./configure script will display warnings if an
+    insecure variation of sprintf() will be used by gzprintf().  Also the
+    zlibCompileFlags() function will return information on what variant of
+    sprintf() is used by gzprintf().
+
+    If you don't have snprintf() or vsnprintf() and would like one, you can
+    find a portable implementation here:
+
+        https://www.ijs.si/software/snprintf/
+
+    Note that you should be using the most recent version of zlib.  Versions
+    1.1.3 and before were subject to a double-free vulnerability, and versions
+    1.2.1 and 1.2.2 were subject to an access exception when decompressing
+    invalid compressed data.
+
+34. Is there a Java version of zlib?
+
+    Probably what you want is to use zlib in Java. zlib is already included
+    as part of the Java SDK in the java.util.zip package. If you really want
+    a version of zlib written in the Java language, look on the zlib home
+    page for links: https://zlib.net/ .
+
+35. I get this or that compiler or source-code scanner warning when I crank it
+    up to maximally-pedantic. Can't you guys write proper code?
+
+    Many years ago, we gave up attempting to avoid warnings on every compiler
+    in the universe.  It just got to be a waste of time, and some compilers
+    were downright silly as well as contradicted each other.  So now, we simply
+    make sure that the code always works.
+
+36. Valgrind (or some similar memory access checker) says that deflate is
+    performing a conditional jump that depends on an uninitialized value.
+    Isn't that a bug?
+
+    No.  That is intentional for performance reasons, and the output of deflate
+    is not affected.  This only started showing up recently since zlib 1.2.x
+    uses malloc() by default for allocations, whereas earlier versions used
+    calloc(), which zeros out the allocated memory.  Even though the code was
+    correct, versions 1.2.4 and later was changed to not stimulate these
+    checkers.
+
+37. Will zlib read the (insert any ancient or arcane format here) compressed
+    data format?
+
+    Probably not. Look in the comp.compression FAQ for pointers to various
+    formats and associated software.
+
+38. How can I encrypt/decrypt zip files with zlib?
+
+    zlib doesn't support encryption.  The original PKZIP encryption is very
+    weak and can be broken with freely available programs.  To get strong
+    encryption, use GnuPG, https://www.gnupg.org/ , which already includes zlib
+    compression.  For PKZIP compatible "encryption", look at
+    http://infozip.sourceforge.net/
+
+39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
+
+    "gzip" is the gzip format, and "deflate" is the zlib format.  They should
+    probably have called the second one "zlib" instead to avoid confusion with
+    the raw deflate compressed data format.  While the HTTP 1.1 RFC 2616
+    correctly points to the zlib specification in RFC 1950 for the "deflate"
+    transfer encoding, there have been reports of servers and browsers that
+    incorrectly produce or expect raw deflate data per the deflate
+    specification in RFC 1951, most notably Microsoft.  So even though the
+    "deflate" transfer encoding using the zlib format would be the more
+    efficient approach (and in fact exactly what the zlib format was designed
+    for), using the "gzip" transfer encoding is probably more reliable due to
+    an unfortunate choice of name on the part of the HTTP 1.1 authors.
+
+    Bottom line: use the gzip format for HTTP 1.1 encoding.
+
+40. Does zlib support the new "Deflate64" format introduced by PKWare?
+
+    No.  PKWare has apparently decided to keep that format proprietary, since
+    they have not documented it as they have previous compression formats.  In
+    any case, the compression improvements are so modest compared to other more
+    modern approaches, that it's not worth the effort to implement.
+
+41. I'm having a problem with the zip functions in zlib, can you help?
+
+    There are no zip functions in zlib.  You are probably using minizip by
+    Giles Vollant, which is found in the contrib directory of zlib.  It is not
+    part of zlib.  In fact none of the stuff in contrib is part of zlib.  The
+    files in there are not supported by the zlib authors.  You need to contact
+    the authors of the respective contribution for help.
+
+42. The match.asm code in contrib is under the GNU General Public License.
+    Since it's part of zlib, doesn't that mean that all of zlib falls under the
+    GNU GPL?
+

+Porting applications to use zlib-ng
+===================================
+
+Zlib-ng can be used/compiled in two different modes, that require some
+consideration by the application developer.
+
+Changes from zlib affecting native and compat modes
+---------------------------------------------------
+Zlib-ng is not as conservative with memory allocation as Zlib is.
+
+Where Zlib's inflate will allocate a lower amount of memory depending on
+compression level and window size, zlib-ng will always allocate the maximum
+amount of memory and possibly leave parts of it unused.
+Zlib-ng's deflate will however allocate a lower amount of memory depending
+on compression level and window size.
+
+Zlib-ng also allocates one "big" buffer instead of doing multiple smaller
+allocations. This is faster, can lead to better cache locality and reduces
+space lost to alignment padding.
+
+At the time of writing, by default zlib-ng allocates the following amounts
+of memory on a 64-bit system (except on S390x that requires ~4KiB more):
+-  Deflate: 350.272 Bytes
+-  Inflate:  42.112 Bytes
+
+**Advantages:**
+- All memory is allocated during DeflateInit or InflateInit functions,
+  leaving the actual deflate/inflate functions free from allocations.
+- Zlib-ng can only fail from memory allocation errors during init.
+- Time spent doing memory allocation systemcalls is all done during init,
+  allowing applications to do prepare this before doing latency-sensitive
+  deflate/inflate later.
+- Can reduce wasted memory due to buffer alignment padding both by OS and zlib-ng.
+- Potentially improved memory locality.
+
+**Disadvantages:**
+- Zlib-ng allocates a little more memory than zlib does.
+
+zlib-compat mode
+----------------
+Zlib-ng can be compiled in zlib-compat mode, suitable for zlib-replacement
+in a single application or system-wide.
+
+Please note that zlib-ng in zlib-compat mode tries to maintain both API and
+ABI compatibility with the original zlib. Any issues regarding compatibility
+can be reported as bugs.
+
+In certain instances you may not be able to simply replace the zlib library/dll
+files and expect the application to work. The application may need to be
+recompiled against the zlib-ng headers and libs to ensure full compatibility.
+
+It is also possible for the deflate output stream to differ from the original
+zlib due to algorithmic differences between the two libraries. Any tests or
+applications that depend on the exact length of the deflate stream being a
+certain value will need to be updated.
+
+**Advantages:**
+- Easy to port to, since it only requires a recompile of the application and
+  no changes to the application code.
+
+**Disadvantages:**
+- Can conflict with a system-installed zlib, as that can often be linked in
+  by another library you are linking into your application. This can cause
+  crashes or incorrect output.
+- If your application is pre-allocating a memory buffer and you are providing
+  deflate/inflate init with your own allocator that allocates from that buffer
+  (looking at you nginx), you should be aware that zlib-ng needs to allocate
+  more memory than stock zlib needs. The same problem exists with Intel’s and
+  Cloudflare’s zlib forks. Doing this is not recommended since it makes it
+  very hard to maintain compatibility over time.
+
+**Build Considerations:**
+- Compile against the *zlib.h* provided by zlib-ng
+- Configuration header is named *zconf.h*
+- Static library is *libz.a* on Unix and macOS, or *zlib.lib* on Windows
+- Shared library is *libz.so* on Unix, *libz.dylib* on macOS, or *zlib1.dll*
+  on Windows
+- Type `z_size_t` is *unsigned __int64* on 64-bit Windows, and *unsigned long* on 32-bit Windows, Unix and macOS
+- Type `z_uintmax_t` is *unsigned long* in zlib-compat mode, and *size_t* with zlib-ng API
+
+zlib-ng native mode
+-------------------
+Zlib-ng in native mode is suitable for co-existing with the standard zlib
+library, allowing applications to implement support and testing separately.
+
+The zlib-ng native has implemented some modernization and simplifications
+in its API, intended to make life easier for application developers.
+
+**Advantages:**
+- Does not conflict with other zlib implementations, and can co-exist as a
+  system library along with zlib.
+- In certain places zlib-ng native uses more appropriate data types, removing
+  the need for some workarounds in the API compared to zlib.
+
+**Disadvantages:**
+- Requires minor changes to applications to use the prefixed zlib-ng
+  function calls and structs. Usually this means a small prefix `zng_` has to be added.
+
+**Build Considerations:**
+- Compile against *zlib-ng.h*
+- Configuration header is named *zconf-ng.h*
+- Static library is *libz-ng.a* on Unix and macOS, or *zlib-ng.lib* on Windows
+- Shared library is *libz-ng.so* on Unix, *libz-ng.dylib* on macOS, or
+  *zlib-ng2.dll* on Windows
+- Type `z_size_t` is *size_t*
+
+zlib-ng compile-time detection
+------------------------------
+
+To distinguish zlib-ng from other zlib implementations at compile-time check for the
+existence of `ZLIBNG_VERSION` defined in the zlib header.

+
+History
+-------
+
+The motivation for this fork was seeing several 3rd party contributions with new optimizations not getting
+implemented into the official zlib repository.
+
+Mark Adler has been maintaining zlib for a very long time, and he has done a great job and hopefully he will continue
+for a long time yet. The idea of zlib-ng is not to replace zlib, but to co-exist as a drop-in replacement with a
+lower threshold for code change.
+
+zlib has a long history and is incredibly portable, even supporting many systems that predate the Internet.<br>
+That is great, but it can complicate further development and maintainability. The zlib code contains many workarounds
+for really old compilers or to accommodate systems with limitations such as operating in a 16-bit environment.
+
+Many of these workarounds are only maintenance burdens, some of them are pretty huge code-wise. With many workarounds
+cluttered throughout the code, it makes it harder for new programmers with an idea/interest for zlib to contribute.
+
+I decided to make a fork, merge all the Intel optimizations, some of the Cloudflare optimizations, plus a couple other
+smaller patches. Then started cleaning out workarounds, various dead code, all contrib and example code.<br>
+The result is a better performing and easier to maintain zlib-ng.
+
+A lot of improvements have gone into zlib-ng since its start, and numerous people and companies have contributed both
+small and big improvements, or valuable testing.
+
+

+
+Install
+-------
+
+WARNING: We do not recommend manually installing unless you really know what you are doing, because this can
+potentially override the system default zlib library, and any incompatibility or wrong configuration of zlib-ng
+can make the whole system unusable, requiring recovery or reinstall.
+If you still want a manual install, we recommend using the /opt/ path prefix.
+
+For Linux distros, an alternative way to use zlib-ng (if compiled in zlib-compat mode) instead of zlib, is through
+the use of the _LD_PRELOAD_ environment variable. If the program is dynamically linked with zlib, then the program
+will temporarily attempt to use zlib-ng instead, without risking system-wide instability.
+
+```
+LD_PRELOAD=/opt/zlib-ng/libz.so.1.2.13.zlib-ng /usr/bin/program
+```
+
+### Cmake
+
+To install zlib-ng system-wide using cmake:
+
+```sh or powershell
+cmake --build . --target install
+```
+
+### Configure
+
+To install zlib-ng system-wide using the configure script:
+
+```sh
+make install
+```
+
+### CPack
+
+After building with cmake, an installation package can be created using cpack. By default a tgz package is created,
+but you can append `-G <format>` to each command to generate alternative packages types (TGZ, ZIP, RPM, DEB). To easily
+create a rpm or deb package, you would use `-G RPM` or `-G DEB` respectively.
+
+```sh or powershell
+cd build
+cpack --config CPackConfig.cmake
+cpack --config CPackSourceConfig.cmake
+```
+
+### Vcpkg
+
+Alternatively, you can build and install zlib-ng using the [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager:
+
+```sh or powershell
+git clone https://github.com/Microsoft/vcpkg.git
+cd vcpkg
+./bootstrap-vcpkg.sh # "./bootstrap-vcpkg.bat" for powershell
+./vcpkg integrate install
+./vcpkg install zlib-ng
+```
+
+The zlib-ng port in vcpkg is kept up to date by Microsoft team members and community contributors.
+If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
+
+Contributing
+------------
+
+Zlib-ng is aiming to be open to contributions, and we would be delighted to receive pull requests on github.
+Help with testing and reviewing pull requests etc is also very much appreciated.
+
+Please check the Wiki for more info: [Contributing](https://github.com/zlib-ng/zlib-ng/wiki/Contributing)
+
+Acknowledgments
+----------------
+
+Thanks go out to all the people and companies who have taken the time to contribute
+code reviews, testing and/or patches. Zlib-ng would not have been nearly as good without you.
+
+The deflate format used by zlib was defined by Phil Katz.<br>
+The deflate and zlib specifications were written by L. Peter Deutsch.
+
+zlib was originally created by Jean-loup Gailly (compression) and Mark Adler (decompression).

+   Decode literal, length, and distance codes and write out the resulting
+   literal and match bytes until either not enough input or output is
+   available, an end-of-block is encountered, or a data error is encountered.
+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:
+
+        state->mode == LEN
+        strm->avail_in >= INFLATE_FAST_MIN_HAVE
+        strm->avail_out >= INFLATE_FAST_MIN_LEFT
+        start >= strm->avail_out
+        state->bits < 8
+
+   On return, state->mode is one of:
+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm->avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - On some architectures, it can be significantly faster (e.g. up to 1.2x
+      faster on x86_64) to load from strm->next_in 64 bits, or 8 bytes, at a
+      time, so INFLATE_FAST_MIN_HAVE == 8.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm->avail_out >= 258 for each loop to avoid checking for
+      output space.

+    /* hold is a local copy of strm->hold. By default, hold satisfies the same
+       invariants that strm->hold does, namely that (hold >> bits) == 0. This
+       invariant is kept by loading bits into hold one byte at a time, like:
+
+       hold |= next_byte_of_input << bits; in++; bits += 8;
+
+       If we need to ensure that bits >= 15 then this code snippet is simply
+       repeated. Over one iteration of the outermost do/while loop, this
+       happens up to six times (48 bits of input), as described in the NOTES
+       above.
+
+       However, on some little endian architectures, it can be significantly
+       faster to load 64 bits once instead of 8 bits six times:
+
+       if (bits <= 16) {
+         hold |= next_8_bytes_of_input << bits; in += 6; bits += 48;
+       }
+
+       Unlike the simpler one byte load, shifting the next_8_bytes_of_input
+       by bits will overflow and lose those high bits, up to 2 bytes' worth.
+       The conservative estimate is therefore that we have read only 6 bytes
+       (48 bits). Again, as per the NOTES above, 48 bits is sufficient for the
+       rest of the iteration, and we will not need to load another 8 bytes.
+
+       Inside this function, we no longer satisfy (hold >> bits) == 0, but
+       this is not problematic, even if that overflow does not land on an 8 bit
+       byte boundary. Those excess bits will eventually shift down lower as the
+       Huffman decoder consumes input, and when new input bits need to be loaded
+       into the bits variable, the same input bits will be or'ed over those
+       existing bits. A bitwise or is idempotent: (a | b | b) equals (a | b).
+       Note that we therefore write that load operation as "hold |= etc" and not
+       "hold += etc".
+
+       Outside that loop, at the end of the function, hold is bitwise and'ed
+       with (1<<bits)-1 to drop those excess bits so that, on function exit, we
+       keep the invariant that (state->hold >> state->bits) == 0.

-   returns 852, and "enough 30 6 15" for distance codes returns 592. The
