Hi all,

        There's a pull request for a lightning payment format which I'd
love wider review on.  It's bech32 encoded, with optional parts tagged:

        https://github.com/lightningnetwork/lightning-rfc/pull/183

There's an implementation with a less formal description here, too:

        https://github.com/rustyrussell/lightning-payencode

Example:
        Send 2500 microbitcoin using payment hash 00010203040506...0102 to me
        @03e7156ae33b0a208d0744199163177e909e80176e55d97a2f221ede0f934dd9ad
        within 1 minute from now (Tue 30 May 12:17:36 UTC 2017):
