-- Export everything from legends mode
--[[=begin

exportlegends
=============
Controls legends mode to export data - especially useful to set-and-forget large
worlds, or when you want a map of every site when there are several hundred.

The 'info' option exports more data than is possible in vanilla, to a
:file:`region-date-legends_plus.xml` file developed to extend
:forums:`World Viewer <128932>` and other legends utilities.

Options:

:info:  Exports the world/gen info, the legends XML, and a custom XML with more information
:custom Exports a custom XML with more information
:sites: Exports all available site maps
:maps:  Exports all seventeen detailed maps
:all:   Equivalent to calling all of the above, in that order
