wormhole — ephemeral pipe relay
================================

  Sender:    curl -fsS https://wormhole.ajxchapman.com/send | bash -s -- [OPTIONS] [DIR]
  Receiver:  curl -fsS https://wormhole.ajxchapman.com/recv/<ID> | bash -s -- [OPTIONS] [SECRET] [DIR]
             (just copy-paste the command the sender prints)

By default the transfer is ENCRYPTED (AES-256-CBC, key derived from a 64-char
hex SECRET shared out-of-band) and ONE-SHOT (sender tars everything, receiver
extracts everything).

Sender flags:
  --plain                    don't encrypt (relay sees plaintext)
  --sync                     rsync-style: only newer/missing files travel
  --id ID                    reuse a specific channel id
  -x, --exclude PATTERN      extra exclude pattern (repeatable)
  --no-default-excludes      disable built-in excludes
  --install                  print 'wormhole' shell alias to stdout, then exit
  -h, --help                 full help

Receiver flags (mirror whatever the sender chose):
  --plain                    sender used --plain
  --sync                     sender used --sync
  -f, --force                overwrite newer files at destination
                             (default: --keep-newer-files protects them)

Default excludes: .git .hg .svn node_modules __pycache__ *.pyc *.pyo .DS_Store Thumbs.db

Channels are ephemeral, single-use, idle-timed-out. UUIDs are unguessable.
