--[=[
The following values are recognized for each script label:

'description'
  A plain English description for the label. Special template substitutions are recognized; see below.
'umbrella_parents'
  A table listing one or more parent categories of the umbrella category 'LABELS by script' for this label.
  The format is as for regular raw categories (see [[Module:category tree/poscatboiler/data/documentation]]).
'umbrella_breadcrumb'
  The breadcrumb to use in the umbrella category 'LABELS by script'. Defaults to "by script".
'catfix'
  Same as the 'catfix' parameter for regular raw categories (see [[Module:category tree/poscatboiler/data/documentation]]).
  This specifies a language code to use to ensure that pages in the category are displayed in the right font and linked
  appropriately. If this is set, the 'catfix_sc' parameter will effectively be set with the script code in question.

Special template-like parameters can be used inside the 'description' field (as well as in the 'root_description', 'root_intro' and
'root_additional' variable values initialized below). These are replaced by the equivalent text.

{{{code}}}: Script code.
{{{codes}}}: A comma-separated list of all the alias codes for this script. This applies especially to Arabic, which has
  multiple aliases (e.g. 'tt-Arab', 'ur-Arab', 'ku-Arab', etc.).
{{{codesplural}}}: The value "s" if {{{codes}}} lists more than one code, otherwise an empty string.
{{{scname}}}: The name of the script that the category belongs to.
{{{sccat}}}: The name of the script's main category, which adds "script" to the capitalized regular name.
{{{scdisp}}}: The display form of the script, which adds "script" to the regular name.
{{{scprosename}}}: Same as {{{scdisp}}} for Morse code and flag semaphore, otherwise adds "the" before {{{scdisp}}}.
{{{Wikipedia}}}: The Wikipedia article for the script (if it is present in the language's data file), or else {{{sccat}}}.
