class macOSPythonBuilder : PythonBuilder {

<#
|
|
.SYNOPSIS
|
|
MacOS Python builder class.
|
|
|
|
.DESCRIPTION
|
|
Contains methods that required to build macOS Python artifact from sources. Inherited from base NixPythonBuilder.
|
|
|
|
While python.org provides precompiled binaries for macOS, switching to them risks breaking existing customers.
|
|
If we wanted to start using the official binaries instead of building from source, we should avoid changing previous versions
|
|
so we remain backwards compatible.
|
|
|
|
.PARAMETER platform
|
|
The full name of platform for which Python should be built.
|
|
|
|
.PARAMETER version
|
|
The version of Python that should be built.
