Re:Single-file scripts that download their dependencies

From the linked docs, it's not obvious to me how I could use this tool in the way TFA uses nix-shell to resolve script dependencies.

You just use the dependencies, for example:
$ cat /tmp/hello.py
#! /opt/appfs/rkeene.org/python3/platform/latest/bin/python3
print("Hello, world!".rjust(20, "-"))
$ /tmp/hello.py
-------Hello, world!

The really nice thing about the nix-shell example is I can specify external python dependencies within the script itself, and even the python version itself, all within one file, and nix-shell just takes care of it.

If you change `latest` to the version [0], then you'll get that exact version.
Additionally any external dependencies can be specified by just accessing them the same way you would in `nix-shell`, just using the path instead of installing. For example, if you wanted to use the "awscli" (the only Python package I already created within AppFS) you would do:
$ cat /tmp/aws.py
#! /opt/appfs/rkeene.org/python3/platform/latest/bin/python3
import sys
sys.path.append('/opt/appfs/rkeene.org/aws-cli/platform/latest/lib/python3.6/site-packages')
import awscli
print(awscli)
$ /tmp/aws.py
<module 'awscli' from '/opt/appfs/rkeene.org/aws-cli/platform/latest/lib/python3.6/site-packages/awscli/__init__.py'>
