Bump support up to FreeBSD 13 and NetBSD 9.2
These releases are really exciting since they contained the patches we worked to get upstreamed. It means that their /bin/sh interpreters all work fine with Actually Portable Executable now.

# SYNOPSIS
|
||||
#
|
||||
# Actually Portable Python Tutorial
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This tutorial demonstrates how to compile Python apps as tiny
|
||||
# static multiplatform APE executables as small as 1.9m in size
|
||||
# using Cosmopolitan, which is a BSD-style multitenant codebase
|
||||
#
|
||||
# GETTING STARTED
|
||||
#
|
||||
# # run these commands after cloning the cosmo repo on linux
|
||||
# $ make -j8 o//examples/pylife/pylife.com
|
||||
# $ o//examples/pylife/pylife.com
|
||||
# cosmopolitan is cool!
|
||||
#
|
||||
# HOW IT WORKS
|
||||
#
|
||||
# $ pyobj.com -m -o pylife.o pylife.py
|
||||
# $ ld -static -nostdlib -T o//ape/ape.lds ape.o crt.o \
|
||||
# pylife.o \
|
||||
# cosmopolitan-python-stage2.a \
|
||||
# cosmopolitan-sqlite3.a \
|
||||
# cosmopolitan-linenoise.a \
|
||||
# cosmopolitan-bzip2.a \
|
||||
# cosmopolitan-python-stage1.a \
|
||||
# cosmopolitan.a
|
||||
# $ ./pylife.com
|
||||
# cosmopolitan is cool!
|
||||
#

||||
# NOTES

||||
# If you enjoy this tutorial, let us know jtunney@gmail.com. If
|

# you're building something cool, then we can we can add you to
|

# our .gitowners file which grants you commit access so you can
|

# indepnedently maintain your package, as part of the mono-repo
