This module and associated sub-modules support the Citation Style 1 (en.wiki) and Citation Style 2 (en.wiki) citation templates. In general, it is not intended to be called directly, but is called by one of the core CS1 and CS2 templates.

These files comprise the module support for cs1|2 citation templates:
