#=== HELP START ===
# run.sh – local wrapper for the “deb-changelog-action”
#
# Behaviour:
# • Clones https://git.0xmax42.io/actions/deb-changelog-action at the requested version into a temporary directory.
# • Installs git-cliff via the action’s helper script.
# • Generates a Debian-style changelog **in the current working directory** via the action’s generator script.
#
# Usage:
# ./run.sh --version v0 \
# --tag v2.9.1 \
# --package_name mypkg \
# --author_name "Max Mustermann" \
# --author_email max@example.com \
# [--output_file debian/changelog] \
# [--cliff_config path/to/cliff.toml]
#
# Options:
# --version <ver> Action version to clone (required)
# --tag <tag> Git tag used as starting point (required)
# --package_name <name> Debian package name (required)
# --author_name <name> Changelog author name (required)
# --author_email <mail> Changelog author e-mail (required)
# --output_file <file> Changelog path (default: debian/changelog)
# --cliff_config <file> git-cliff config file (default: configs/cliff.debian.toml)
# -h, --help Show this help message
#
# Notes:
# • Paths given for --output_file are interpreted relative to the directory
# where you run this script.
# • If --cliff_config is omitted, the default config shipped with the action
# (configs/cliff.debian.toml) is used.
# • PACKAGE_NAME, AUTHOR_NAME, AUTHOR_EMAIL are exported so the TOML template
# can reference them (e.g. {{ get_env(name="PACKAGE_NAME") }}).
