bgfx shading language reference

[mnesarco]

Hi Friends,
Is there any documentation about the proprietary bgfx shading language?

I have found only two resources:

https://bkaradzic.github.io/bgfx/tools.html#shader-compiler-shaderc
https://github.com/bkaradzic/bgfx/blob/master/src/bgfx_shader.sh
But both are almost useless to learn the language. I suppose that for people that already knows glsl it is easy to get the idea, but for newbies it is just another languaje to learn.

I am just learning, and all shading languages (glsh, hlsl, msl and bgfx_sl) are new to me. I prefer to start learning bgfx_sl because I am learning bgfx.

Thanks.
