Why the build script can't have a command line interface?
It could, but now the build script is a more complicated and
for little gain.
It's only as complicated to implement required features and not
more complicated. If the command line interface is not needed, it
can be omitted, example:
---
import button;
auto Build = ...
mixin mainBuild!Build; //no CLI
---
Adding command line options on top of that to configure the
build would be painful.
$ rdmd build.d configure [options]
Well, if one wants to go really complex, a prebuilt binary can be
provided to help with that, but it's not always needed I think.
It would be simpler and cleaner to write a D program to
generate the JSON build description for Button to consume. Then
you can add a command line interface to configure how the build
description is generated. This is how the Lua build
descriptions work[1].

import button;
auto Build = ...

Should be possible to work like lua script.
