Currency Exchange

Currency exchange app using ExchangeRate-API.
To use, need ExchangeRate-API Key which is obtainable here

Arguments:
  [Currency input]   Currency code to exchange from
  [Currency target]  Currency code to exchange to
  [Amount]           Currency amount to exchange

Options:
  -k, --set-api-key <API_KEY>  Set api key
  -r, --recreate-cache         Recreate cache

Cache and api key is stored by default in <XDG_CACHE_HOME>/currencyCache.db or <TMPDIR>/currencyCache.db if XDG_CACHE_HOME is not set. This location and filename can be overriden by setting up CURRENCY_CACHE env variable.
