usage_description="
Exports all TeamCity BuildTypes (build pipelines) to local JSON configuration files for backup/restore / migration purposes, or even just to backport changes to Git for revision control tracking

If arguments are specified then only downloads those named BuildTypes, otherwise finds and downloads all BuildTypes

Uses the adjacent teamcity_api.sh and jq (installed by 'make')

See teamcity_api.sh for required connection settings and authentication
