// This sample program serves purley as a way to interactively test the features
// of RCW before building it into your own application.
//
// Usage:
// rcw <text> : Runs the rcw daemon to serve the provided text for three minutes
// rcw : Requests the data served by the RCW daemon and outputs it to stdout
// rcw enc <text> <passwd> : Encrypts the provided text and outputs the ciphertext to encrypted-example.txt
// rcw dec <passwd> : Decrypts the provided file and outputs the plaintext to stdout
