usage_description="
Sets the description of a BitBucket.org repo via the BitBucket API

Uses the adjacent script bitbucket_api.sh, see there for authentication details

\$CURL_OPTS can be set to provide extra arguments to curl


Repo should be specified as <workspace>/<repo> using the slugs which are usually just the same as the username and repo lowercase (they're case sensitive, eg. harisekhon/devops-bash-tools)

Repo workspace prefix, if not set, is assumed to be the username and will use \$BITBUCKET_USER if available, otherwise will query the BitBucket API to determine it


If you get an error it's possible you don't have the right token permissions.
You can generate a new token with the right permissions here:

    https://bitbucket.org/account/settings/app-passwords/


Example:

${0##*/} harisekhon/devops-bash-tools    my new description


If no args are given, will read read and description from standard input for easy chaining with other tools, can easily update multiple repositories this way, one repo + description per line:

echo <repo> <description> | ${0##*/}
"

# shellcheck disable=SC2034
