Yep, it should work with 3.6. There were scripts under Tools/msi back <br>
then that did the same thing, but with the Store app I rewrote it to be <br>
more flexible.<br>

<br>
Probably not, it's under the "PC" directory because it is entirely <br>
CPython specific.<br>
<br>
I'd love to be able to have a similar embeddable distro for Linux (and <br>
macOS), and I'll be investing some of my time in working towards this, <br>
but it's far more complicated than simply laying out the right files. If <br>
you're interested in helping with this, then we're in the right place to <br>
discuss it, but we'll likely have to move to the issue tracker at some <br>
point once we figure out who else wants/needs to be involved.<br>

<br>
"make install" already does the same thing, but the install location <br>
matters at build time, so it's a little more complex to make it work as <br>
an embedded runtime. I'm sure there are people who know how to make it <br>
work though.<br>
