These are patterns for cs1 templates and their redirects. These patterns exclude redirects that are vcite-like
which redirects should be deleted because vcite is not cs1.

These are patterns for the harvc template and its redirects.


local harvc_template_patterns = {
	'[Hh]arvc',																	-- canonical

------------------------------------------------------

These are patterns for miscellaneous templates and their redirects that 'look like' cs1 templates (begin with cite ...)

Because they 'look like' cs1 templates they are handled as if they were cs1 templates. These templates are NOT
wrapper templates; names and dates are always to be extracted from the article instantiation of the template.


local cs1_like_template_patterns = {
	'[Cc]ite LSA',																-- canonical

------------------------------------------------------

These are patterns for the wikicite template and its redirects.

----------------------------------------------------------

These are patterns for the anchor template and its redirects.


local anchor_template_patterns = {
	'[Aa]nchors?',																-- anchor is canonical form
	'[Aa]nchor for redirect',
	'[Aa]nchro',
	'[Aa]ncor',

--------------------------------------------------------------

These are patterns for the anchor template and its redirects.

		'[Hh]arv whitelist',

--[[--------------------------------------------------------------------------

These tables are created from the *_template_patterns tables. To make these tables, entries in the source tables
are evaluated to replace lua patterns with the appropriate characters to create names for the output tables.

First charqacter is always uppercase

For example:
	[Cc]ite ar[Xx]iv
becomes
	Cite arXiv
	Cite arxiv
