# Script's guidelines:

#* uses 'CURRENCY=TESTKUDOS' and uses $CURRENCY for all
#  currencies in what follows ...
#* for databases, use either 'anastasischeck' for Postgres
#  or an sqlite file created via "mktemp /tmp/test-XXXXXX"
#  or something like that
#* exits with 77 if libeufin is not properly installed/available
#  installed/available
#* starts Nexus (in background)
#* starts sandbox (in background)
#* creates two IBAN accounts
#* stores IBANs of both accounts in shell variables,
#  call them IBAN_CREDIT and IBAN_DEBIT.
#* configures an Anastasis facade for IBAN_CREDIT.
#* exports authentication credentials (URL, access token)
#  for the facade to shell variables
#  (FACADE_URL, FACADE_AUTH_TOKEN)
#  ~~~~~~~~~
#* contains a command to do a wire-transfer (pick your amount)
#  from DEBIT to CREDIT (setup authentication as needed to
#  trigger the transfer)
