Slide Show (S9) v4 Update - v.4 Update - Write Your Talks / Slides in Plain Text (w/ Jekyll Themes)

Hello,

    I've updated the Slide Show (S9) command line tool (and
library/gem) [1] that lets you write your talks / slides /
presentations in plain text w/ markdown conventions.
Example:

    # Blockchain! Blockchain! Blockchain! Decentralize Payments.
Decentralize Transactions. Decentralize Blockchains.

   What's Blockchain?

    - Distributed Database?
    - Hyper Ledger Book?
    - Consensus with Proof-of-Work or Proof-of-Stake?
    - Digital Fingerprints? Cryptographic Hashes?
    - Lottery? Central Bank?
    - Byzantine-Generals Solution?

    Yes. Yes. Yes. Blockchain! Blockchain! Blockchain!

    # The Proof of the Pudding is ... The Bitcoin (BTC) Blockchain(s)

    A Success Story on the Blockchain.

    May 22, 2010 - World's 1st Bitcoin Payment

    A developer bought two pizzas using 10 000 Bitcoin (BTC) - a
then-little-known digital (crypto)currency.
    Estimated worth about $40.

    Triva Q: How much is one Bitcoin worth today? Q: How much are 10
000 Bitcoin worth today?

  Note: You can use any of the (Jekyll-compatible) theme packs [2]
such as reveal.js, bespoke.js, s6blank, etc.

   As an example, see the Blockchain! Blockchain! Blockchain! [3] talk
(source in markdown) [4].

     Happy publishing & talking. Cheers.
