m4 contains GNU M4 scripts that are prepended as input files for every M4 call. You can create more of them, but basic template contains only 2 files: vendor for repository default M4 macros and custom for user own macros.

src/include is an include dir that GNU M4 uses when building. Put Your shared logic here. If there is a logic that is used in both core and post shaders You should create a file under src/include and an additional file under minecraft/shaders/include with include(`your_file.glsl') line.

Macros are proccesed by GNU M4. You can override the flags via M4_FLAGS env variable.
