This silly IRC bot knows just a few tricks.

If you message it privately, it will respond privately. Otherwise, it will respond on the channel in which you find it.

After you npm install, just

$ node index.js --server irc.example.com --port 6697 --username whateverbot --channels '#chan1 #chan2'

e.g.

!help [!cmd] gives you help, optionally about the command `!cmd'.

!btc gives you the current market price for Bitcoin, according to Blockchain.info.

!sha1 val will give you the SHA1 hash value of val, in hex.

!encode inFmt outFmt arg1 [arg2 [... argn]] will use node Buffers to reencode each argument from inFmt to outFmt (see https://nodejs.org/api/buffer.html#buffer_buffer).

!reddit [reddit] will fetch a random link from the subreddit named reddit, or will use random as reddit if omitted.

!lfa arg1 [arg2 [... argn]] performs a letter frequency analysis on the characters of all the arguments.

!rot shift arg1 [arg2 [... argn]] performs a rotational cipher of order shift to each argument, leaving non-letter values untouched.
