"""
Reads a tox profile and prints out information on what's in there to stderr.

Call it with one argument, the filename of the profile for the decrypt or info
commands, or the filename of the nodes file for the nodes command.

4 commands are supported:
--command info - default
  prints info about what's in the Tox profile to stderr

--command nodes
  assumes you are reading a json nodes file instead of a profile

--command decrypt
  decrypts the profile and writes to the result to stdout

--command edits
  edits fields in a Tox profile with --output to a file

--command onions
  cleans or checks a /etc/tor/torrc file with --output to a file
