WARP - how to try the todos example

• warp project: on github
• also on docs.rs
• todos.rs example https://github.com/seanmonstar/warp/blob/master/examples/todos.rs

After starting the example (cargo run --example todos) following are some handy curl commands

create

pkozelka

#!/bin/bash
# Indicated files will be renamed by prefixing with their modification date.
# Useful for photos from old devices that did not store metadata.

# This only prints the `mv` commands (preview); pipe it to `sh` to apply the changes

function filetime() {
	local f=$1
	local t=$(stat -c %y "$f")
	t=${t%% *}
