Hello,

I have been tinkering around the PackageCompiler module.  
I’ve been trying to build various system images with my most used packages to speed up the workflow (so far no success).

I must admit that i am really confused about the state of the package. Is it in a usable state?  
If so, are there up to date documentations?  
What’s the difference between the `master` branch and the `sd-notoml` one?

Thanks!

It is better to use PackageCompilerX, this is the new package that is updated regularly

so PackageCompiler is now deprecated, in favor of PackageCompilerX?
