include cli?

[tmc]

seems like it'd be handy

Sure, I've planned it to add.

I think the tool should do:

• read from stdin or file and send the outout to the sdtout or file in various formats including custom templating(unix way)
• serve HTTP request(rest api service)

@tmc, could you describe your use-case?

Reading from flags can also be useful. Take GNU date for example:

date +%s -d 'tomorrow 9:00 am'
# Prints `1484398800` to stdout (i.e. 2017-01-14 09:00:00 in unix time).
