אונטערשייד צווישן ווערסיעס פון "יחידה:ParamValidator"

the source of this module is in //he.wikipedia.org/wiki/Module:ParamValidator

This module exports two functions: calculateViolations( frame, subpages ), and validateParams( frame ).  

it expects a parameter named "options", which contains the definition of the output. typically, it's used by placing something like so:

at the top of the template (be mindful not to add extra spaces and newlines to the template).

the options parameter should be a JSON-encoded string, defining the output, and some special behaviors.  

typically, this JSON structure will be placed in a separate template, and retrieved for the module-use as shown above.

"key" can override any of the options fields described above.
