Thank you for your quick responses and suggestions!

I managed to move forward a bit, but there's a lot of "friction".
Quick try of compiling CFEngine on Alpine Linux failed, so I just settled=
=20
on the "symlink hack" for now.
I also know more or less how to hook up to the MPF so it runs my policies.

Got quick two questions:
1. Can strings in CFEngine be split up into multiline without defining=20
additional variables, and without adding unintended whitespaces?
E.g. In C++ I'd do something like this:
```
const char* string =3D "This is my first line,"
" this is another line";
```
Which evaluates to "This is my first line, this is another line"
2. Can I build my own bundles/functions which return values? I've seen that=
=20
bundles can modify variables and define class in the parent scope, but that=
=20
seems quite horrible. I mean something like this:
```
vars:
    "my_value" string =3D> do_http_request("some arguments here");
```
where "do_http_request" is some wrapper around Curl that I can write on my=
=20
own,
can't use url_get, because the binary on Alpine is compiled without curl=20
support, and I would rather not bother with that,
and instead do what I would do in other languages: abstract the mundane=20
task of calling curl into something less repetitive.
