Description

I was curious about how executable zip file of youtube-dl works then found it's using a patched py2exe. (windows)
The idea is awesome and useful. but it can't be used on other projects and it's pity.

python2.7 will not be supported very soon.
would you like to move the building part of youtube-dl from 2.7 to 3.x(>4)? and it'll also be great if the executable system can also be used on other projects. since the zipapp module feels terriable.

thanks

Exe is built with python 3.4.

then https://www.python.org/downloads/release/python-3410/ python 3.4 is already retired.

the main point I meant is the would you like to make package part a new project.
