 This proposal affects two components of packaging: `the pip bootstrap`_ and,
 thanks to easier package installation, `modifications to publishing
 packages`_.

 The Python installation includes an executable called "pip3" (see PEP 394 for

 A boostrap is used in the place of a the full pip code so that we don't have
 to bundle pip and also pip is upgradeable outside of the regular Python

 The required code for this implementation is the "pip3" command described

 PEP's work.
