Usage: tegawa [options]

TeGaWa stands for Telegram GateWay. This tool is supposed to be run
as a daemon and accept local mail as well as watch a directory for
text files. It then forwards these mails and files to a Telegram
channel so you can easily stay informed about what is happening on
your systems.

It expects $TEGAWA_TOKEN to contain your telegram bot token and it
needs the channel_id to which it forwards the information.
