We need to say here that VS 2017 will not work. Ordinary people will not assume
a specific version dependency.

[sergei, 2017/05/31 12:47:10]

Should we say in addition that VS 2020 and 2030 will not work? BTW, 2017 maybe
does work, at least as editor, I have not tested on it.

I have changed this line to a new one mentioning minimal toolset because other
lines are about compilers, not about IDE.

Again, this should say that the C++ version in VS 2017 will not work.

Is there actually a toolset upgrade required? Yes, and it's hard-coded to an old
version, and that version isn't listed here.

It looks like this should say "You need Microsoft Visual Studio 2015 installed
with the default directories". There's a dependency on a hard coded path name
for "vcvars32.bat".

I'm not sure about it, as far as I know it's possible to install v140 toolset in
MSVS 2017, and v141 should be compatible with v140, so maybe it does work there.
The toolset is added above where compilers are listed.
I have added that it's tested with MSVS 2015 CE, it will be updated as soon as
we know whether it works with MSVS 2017 and what actions are required.

 and Python 2.7. Make sure that `python.exe` is on your `PATH`.
