A minimal IRC bot that was built for me, not you.
go get github.com/bbriggs/bitbot && go install github.com/bbriggs/bitbot
Assuming that $GOPATH/bin is in your $PATH:
bitbot run --server=irc.someserver.com:6697 --channels="#foo,#bar" --nick=bitbot --ssl
Or with Docker:
docker run -d -it bbriggs/bitbot run --server=irc.someserver.com:6697 --channels="#foo,#bar" --nick=bitbot --ssl
