-- Convert regular Gettext PO files to Minetest-specific TR files. If there is
-- already a TR file with the same name of the PO file except the file suffix
-- bneing .tr (or .TR) instead of .po (or .PO) then THIS FILE WILL BE
-- OVERWRITTEN WITHOUT INFORMATION OR A WAY TO RECOVER THE PREVIOUS FILE!

-- The syntax of TR files according to the introducing forum post is:
--
-- # textdomain: namespace
-- original 1 = translation 1
-- original 2 = translation 2
-- original 3 = tralslation 3
-- original N = translation N
--
-- Where namespace should be the name of the mod. Following strings have to be
-- escaped using @.
--
-- String | Escape
-- -------+--------
-- `@` |`@@`
-- `=` |`@=`
-- `\n` |`@\n`
--
-- See https://forum.minetest.net/viewtopic.php?t=18349 for details.
