var event = &cli.Command{
Name: "event",
Usage: "generates an encoded event and either prints it or sends it to a set of relays",
Description: `example usage (for sending directly to a relay with 'nostcat'):
nak event -k 1 -c hello --envelope | nostcat wss://nos.lol
standalone:
nak event -k 1 -c hello wss://nos.lol`,
Description: `outputs an event built with the flags. if one or more relays are given as arguments, an attempt is also made to publish the event to these relays.
example:
nak event -c hello wss://nos.lol
nak event -k 3 -p 3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d
if an event -- or a partial event -- is given on stdin, the flags can be used to optionally modify it. if it is modified it is rehashed and resigned, otherwise it is just returned as given, but that can be used to just publish to relays.
example:
echo '{"id":"a889df6a387419ff204305f4c2d296ee328c3cd4f8b62f205648a541b4554dfb","pubkey":"c6047f9441ed7d6d3045406e95c07cd85c778e4b8cef3ca7abac09b95c709ee5","created_at":1698623783,"kind":1,"tags":[],"content":"hello from the nostr army knife","sig":"84876e1ee3e726da84e5d195eb79358b2b3eaa4d9bd38456fde3e8a2af3f1cd4cda23f23fda454869975b3688797d4c66e12f4c51c1b43c6d2997c5e61865661"}' | nak event wss://offchain.pub

it can also take a filter from stdin, optionally modify it with flags and send it to specific relays (or just print it).
