-- This provides categories and documentation for various data modules, so that
-- [[ကဏ္ဍ:Uncategorized modules]] isn’t unnecessarily cluttered.
-- It is a list of tables, each of which have three possible fields:

-- The “regex” field is required. It is a Lua pattern to match the module’s
-- title. If it matches, the data will be used. If the pattern contains one
-- capture, and a category has been specified, the capture will be used as a
-- sortkey.

-- The “doc” field is required. This may be a function or a
-- string. If it is a function, it receives a title and an array (see
-- [[မော်ဂျူး:array]]) of categories that will be added to the documentation as
-- its first and second arguments, and may return a string, which will be used
-- as documentation. If it is a string, it is the name of a submodule under
-- “Module:Wt/rki/documentation/functions/” which returns a function, of the same type
-- as described above.

-- The “cat” field is optional. It is a category in which the module should be
-- placed. The inner part of the category link is generated as follows:
-- mw.ustring.gsub(full_title, cat_field)
-- So if the “cat” field is present, the “regex” field should match the whole
-- title, and if there is “|%1” at the end of the “cat” field, for a sortkey,
-- there should be one capture in the “regex” field.
