"""
This script is used to build "official" universal installers on macOS.
NEW for 3.9.0 and backports:
- 2.7 end-of-life issues:
- Python 3 installs now update the Current version link
in /Library/Frameworks/Python.framework/Versions
- fully support running under Python 3 as well as 2.7
- support building on newer macOS systems with SIP
- fully support building on macOS 10.9+
- support 10.6+ on best effort
- support bypassing docs build by supplying a prebuilt
docs html tarball in the third-party source library,
in the format and filename conventional of those
downloadable from python.org:
python-3.x.y-docs-html.tar.bz2
NEW for 3.7.0:
- support Intel 64-bit-only () and 32-bit-only installer builds
- build and use internal Tcl/Tk 8.6 for 10.6+ builds
- deprecate use of explicit SDK (--sdk-path=) since all but the oldest
versions of Xcode support implicit setting of an SDK via environment
variables (SDKROOT and friends, see the xcrun man page for more info).
The SDK stuff was primarily needed for building universal installers
for 10.4; so as of 3.7.0, building installers for 10.4 is no longer
supported with build-installer.
- use generic "gcc" as compiler (CC env var) rather than "gcc-4.2"
TODO:
- test building with SDKROOT and DEVELOPER_DIR xcrun env variables
Usage: see USAGE variable in the script.
