# Record an asciinema demo of fj. The result is a .cast file you can:
#   - Upload to asciinema.org via `asciinema upload dist/demo.cast`
#   - Embed as a static SVG/GIF via `agg` (https://github.com/asciinema/agg)
#   - Link from README.md
#
# Requires: asciinema, fj (installed and authenticated), `jq` for nicer output.
#
# Usage:
#   ./scripts/record-demo.sh           # records dist/demo.cast
#   ./scripts/record-demo.sh foo.cast  # records to foo.cast
#
# The session below is deliberately short (~30 seconds) and covers what
# someone reading the README in their first 10 seconds cares about.
