Re: [dev] Build system: redo

Here is my attempt at a redo file for st, instead of a Makefile. I expect it is a complete replacement. If it interests any of you, please take a look and give me constructive criticism. Does it have any flaws? Could it be improved? I know that there are advantages to having the .do files separated, so there is no need to mention that. I am choosing one big file for my learning [1].

Attached and included. Thanks in advance.
