:: Start Vim on a copy of the tutor file.
@echo off

:: Usage: vimtutor [-console] [xx]
::
:: -console means gvim will not be used
:: xx is a language code like "es" or "nl".
:: When an xx argument is given, it tries loading that tutor.
:: When this fails or no xx argument was given, it tries using 'v:lang'
:: When that also fails, it uses the English version.

:: Use Vim to copy the tutor, it knows the value of $VIMRUNTIME
