python3-pep517 binary package in Ubuntu Lunar amd64

 This package contains wrappers around the hooks specified by PEP 517. It
 provides:
 .
  - A mechanism to call the hooks in a subprocess, so they are isolated from
    the current process.
  - Fallbacks for the optional hooks, so that frontends can call the hooks
    without checking which are defined.
  - Higher-level functions which install the build dependencies into a
    temporary environment and build a wheel/sdist using them.
 .
 This is the Python 3 version of the package.
