## spanish_organization_number.rb
# By "organization number" we mean an organization NIF (Spanish tax identification number). We don't mean personal NIFs such as DNI/NIE (see `SpanishIdentityNumber` for that).
#
# This class also supports personal NIFs starting with the letters K, L or M, though it's inaccurate to call these "organization numbers". More about these: https://translate.google.co.uk/translate?sl=auto&tl=en&u=https%3A%2F%2Fes.wikipedia.org%2Fwiki%2FN%25C3%25BAmero_de_identificaci%25C3%25B3n_fiscal
#
# It's easier to support them than not to, and means that any such users can provide this number, even though it's represented a bit inaccurately in our system. They're likely to be very rare. Feel free to think up a way to represent it more accurately. (Renaming `spanish_organization_number` to something like `non_dni_or_nie_spanish_tax_identification_number`?)

class SpanishOrganizationNumber
  # NIFs do not have the letter prefixes "I" and "O" since those can be confused for the digits "1" and "0".
  # Don't know why "T" is not a p

# In order for this to work, first go to the TV "General" settings and turn on "Mobile TV On".

# Change this to the actual value.
# First find the TV IP, e.g. from your router's list of connected devices.
# Then run "arp -a" on a computer and you'll see the MAC by its IP.
# Maybe you need to "ssh <the ip>" before it will turn up in arp. Not sure.
