# Extends the standard RPM spec file to enable dynamic construction.  This
# allows for external configuration, boilerplate sharing, templates, and other
# dynamic content creation.  Extensible through contributed functions, this
# project also enables you to deeply integrate RPM building into your own
# workflows.

# See --help for much more detail and the tests directory for examples.
