    * Download the Lua 5.4.x sources tarballs from https://lua.org/ftp/, extract them and copy all files in `src` to `Lua`
 2) Patch the source code for Watcom (optional):
 
-   | GNU Patch                       | DifPat                         |

-   | `patch lopcodes.h lopcodes.pat` | `pat lopcodes.pat lopcodes.h ` |
-   | `patch lutf8lib.c lutf8lib.pat` | `pat lutf8lib.pat lutf8lib.c`  |

    > If no patching program is available mimic the changes in each `.pat` file manually. 
    > Patch changes are minimal and only serve to silence Watcom compiler warnings
 
-3) Build Lua with the following commands: 
-   - `wmake -f wm_dos16.mak` will create `dist/bin/dos16.exe` 
-     which can be run on PC-DOS 2 on an 8088 or better PC
-   - `wmake -f wm_dos4g.mak` will create `dist/bin/dos4g.exe` 
-     which can be run on MS-DOS 5 on an i386 or better PC
