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'>
