+
+    copy this crap, it's open source

+/*
+    This is the main executable, 
+        the objective of this project is to recreate/decompile the original pubg lite launcher, 
+        with the aim of being lighter/more portable/and more compatible, 
+        without the need for the .net crap, 
+        this code is being developed to work with Windows XP Service pack 3 and higher , Linux and Macos.
+
+
+    the project is using CEF 2623 b1401 for windows systems, and CEF 2704 b1415 for linux and macos.
+
+    This program is focused on opening on your potato, so do not use 3D web elements like css3d, webgl etc,
+            because this program may be focused on working with coding in software mode, not on gpus
+
+    why do you want it to work on windows xp?
+        for experiments, and also good portability
+
+
+    
+    Note! The original launcher uses CEF 3578 b1870 so some features may not be available.
+    
+    cef libraries should be c only, 
+        do not include c++ wrappers, they require boring libraries and use __stdcall differently than __cdecl
+
+        you can code this program with c++, but do not include the cef c++ libraries.
+
+    the code for this program must be written with C 89 or C++ 98, 
+            for compatibility with other compilers, and for readability.
+
+        avoid specific compiler calls.
+
+        avoid compiler specific syntax
+
+    the code will use doxygen, so document the implemented code well
+
+
+
+    compatible compilers are Open Watcom 1.9, Visual Studio 2019/2022, clang for macos
+
+    I won't have access to the mac, so I'll leave that in someone else's hands.
+
+
+
+    maybe some original launcher implementations don't work on linux and macos, 
+                    like hiding the launcher window and leaving an icon in the tray
+
+
+    use or create abstractions so that the code is the same on multiple platforms
+
+    The CEF localization files for macOS are messier and uglier, 
+        if you want to use Xcode or Cocoa it will look like this, 
+            if not we will use the manual loading method.
+
+
+    Now an IMPORTANT note, 
+        I put libcef 2623 as libcef_ in the include directory, 
+            and I put libcef 2704 in its place, 
+            in case the program presents any problem, 
+            or some inclusion code for Windows gives problems, 
+            just use a macro and include libcef_ in place of libcef : this feat was done by phikill
